Hi Guys!

First of all... GREAT SITE! The workflow to detect and configure the 
chips it's simple and easy to follow.

After 3 hours reading it, plus lm-sensors package doc, plus google 
search I finally write to you.
Early in the morning I started a ticket, but... after reading more, I 
find out that was incomplete.

Here is my full report. Only thing detected is EEPROM. Nothing about 
HW's health.
Not included here, but I have syslog lines, more than 5000 lines of 
messages from i2c modules. If you think they are needed, just ask for 
them. ;)

This was my procedure to detect sensors

rosita:/# sensors-detect

This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.

It is generally safe and recommended to accept the default answers to all
questions, unless you know what you're doing.

 We can start with probing for (PCI) I2C or SMBus adapters.
 You do not need any special privileges for this.
 Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-i801' for device 00:1f.3: Intel 82801EB ICH5
Probe succesfully concluded.

We will now try to load each adapter module in turn.
Load `i2c-i801' (say NO if built into your kernel)? (YES/no):
Module loaded succesfully.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.

 To continue, we need module `i2c-dev' to be loaded.
 If it is built-in into your kernel, you can safely skip this.
 i2c-dev is not loaded. Do you want to load it now? (YES/no):
 Module loaded succesfully.

 We are now going to do the adapter probings. Some adapters may hang halfway
 through; we can't really help that. Also, some chips will be double 
detected;
 we choose the one with the highest confidence value in that case.
 If you found that the adapter hung after probing a certain address, you can
 specify that address to remain unprobed. That often
 includes address 0x69 (clock chip).

Next adapter: SMBus I801 adapter at 0400
Do you want to scan it? (YES/no/selectively):
Client found at address 0x08
Client found at address 0x44
Probing for `Maxim MAX6633/MAX6634/MAX6635'... Failed!
Client found at address 0x50
Probing for `SPD EEPROM'... Success!
    (confidence 8, driver `eeprom')
Probing for `DDC monitor'... Failed!
Probing for `Maxim MAX6900'... Failed!
Client found at address 0x69

Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

Do you want to scan the ISA bus? (YES/no):
Probing for `National Semiconductor LM78'
  Trying address 0x0290... Failed!
Probing for `National Semiconductor LM78-J'
  Trying address 0x0290... Failed!
Probing for `National Semiconductor LM79'
  Trying address 0x0290... Failed!
Probing for `Winbond W83781D'
  Trying address 0x0290... Failed!
Probing for `Winbond W83782D'
  Trying address 0x0290... Failed!
Probing for `Winbond W83627HF'
  Trying address 0x0290... Success!
    (confidence 8, driver `w83781d')
Probing for `Winbond W83697HF'
  Trying address 0x0290... Failed!
Probing for `Silicon Integrated Systems SIS5595'
  Trying general detect... Failed!
Probing for `VIA Technologies VT82C686 Integrated Sensors'
  Trying general detect... Failed!
Probing for `VIA Technologies VT8231 Integrated Sensors'
  Trying general detect... Failed!
Probing for `ITE IT8705F / IT8712F / SiS 950'
  Trying address 0x0290... Failed!
Probing for `IPMI BMC KCS'
  Trying address 0x0ca0... Failed!
Probing for `IPMI BMC SMIC'
  Trying address 0x0ca8... Failed!

Some Super I/O chips may also contain sensors. Super I/O probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

Do you want to scan for Super I/O sensors? (YES/no):
Probing for `ITE 8702F Super IO Sensors'
  Failed! (skipping family)
Probing for `Nat. Semi. PC87351 Super IO Fan Sensors'
  Failed! (skipping family)
Probing for `SMSC 47B27x Super IO Fan Sensors'
  Failed! (skipping family)
Probing for `VT1211 Super IO Sensors'
  Failed! (0x52)
Probing for `Winbond W83627HF Super IO Sensors'
  Success... found at address 0x0290
Probing for `Winbond W83627THF Super IO Sensors'
  Failed! (0x52)
Probing for `Winbond W83637HF Super IO Sensors'
  Failed! (0x52)
Probing for `Winbond W83697HF Super IO Sensors'
  Failed! (0x52)
Probing for `Winbond W83697SF/UF Super IO PWM'
  Failed! (0x52)
Probing for `Winbond W83L517D Super IO'
  Failed! (0x52)

Do you want to scan for secondary Super I/O sensors? (YES/no):
Probing for `ITE 8702F Super IO Sensors'
  Failed! (skipping family)
Probing for `Nat. Semi. PC87351 Super IO Fan Sensors'
  Failed! (skipping family)
Probing for `SMSC 47B27x Super IO Fan Sensors'
  Failed! (skipping family)
Probing for `VT1211 Super IO Sensors'
  Failed! (skipping family)

 Now follows a summary of the probes I have just done.
 Just press ENTER to continue:

Driver `eeprom' (should be inserted):
  Detects correctly:
  * Bus `SMBus I801 adapter at 0400' (Algorithm unavailable)
    Busdriver `i2c-i801', I2C address 0x50
    Chip `SPD EEPROM' (confidence: 8)

Driver `w83781d' (may not be inserted):
  Misdetects:
  * ISA bus address 0x0290 (Busdriver `i2c-isa')
    Chip `Winbond W83627HF' (confidence: 8)

Driver `w83627hf' (should be inserted):
  Detects correctly:
  * ISA bus address 0x0290 (Busdriver `i2c-isa')
    Chip `Winbond W83627HF Super IO Sensors' (confidence: 9)


 I will now generate the commands needed to load the I2C modules.
 Sometimes, a chip is available both through the ISA bus and an I2C bus.
 ISA bus access is faster, but you need to load an additional driver module
 for it. If you have the choice, do you want to use the ISA bus or the
 I2C/SMBus (ISA/smbus)?

To make the sensors modules behave correctly, add these lines to
/etc/modules:

#----cut here----
# I2C adapter drivers
i2c-i801
i2c-isa
# I2C chip drivers
eeprom
w83627hf
#----cut here----

Do you want to add these lines to /etc/modules automatically? (yes/NO)yes


After doing this, reboot and this is lsmod output

Using /etc/sensors.conf provided with lm-sensors-2.9.0, run sensors -s

Before load eeprom module

rosita:/etc# sensors
No sensors found!

After load eeprom module

rosita:/# sensors  
eeprom-i2c-0-50
Adapter: SMBus I801 adapter at 0400
Memory type:            DDR SDRAM DIMM
Memory size (MB):       512

BUT.... I know I paied for 512 MB of RAM. :)
I don't see anything about CPU Temp, FAN Speed, o anything about my 
hardwares health. :(

After this, I read more and found that I need run 
/usr/share/doc/lm-sensors/config/grab_busses.sh

rosita:/# cd /usr/share/doc/lm-sensors/
rosita:/usr/share/doc/lm-sensors# ls

grab_busses.sh
rosita:/usr/share/doc/lm-sensors/examples/config# cat grab_busses.sh
#!/bin/bash

# This simple shell script grabs the contents of /proc/bus/i2c and 
outputs it
# in sensors.conf format through stdout. You can use it to generate those
# nasty 'bus' statements in config files.

if [ $# = 0 ] ; then
  file=/proc/bus/i2c
elif [ $# = 1 ] ; then
  file="$1"
else
  echo "Syntax: grab_busses [file]" >&2
  exit 1
fi

if [ ! -e "$file" ]; then
  echo "Can't find file \`$file';"\
       "try \`modprobe i2c-proc' for /proc/bus/i2c" >&2
  exit 1
fi

cat -- "$file" | awk \
 '  BEGIN { FS = "\t" }
     { sub(" *$","",$3)
       sub(" *$","",$4)
       printf "bus \"%s\" \"%s\" \"%s\"\n",$1,$3,$4 }
     { nrlines++ }
    END { printf "Total lines: %d\n",nrlines > "/dev/stderr"  }
 '
rosita:/usr/share/doc/lm-sensors/examples/config# ./grab_busses.sh
Can't find file `/proc/bus/i2c'; try `modprobe i2c-proc' for /proc/bus/i2c
rosita:/usr/share/doc/lm-sensors/examples/config#

But... As I explained early, I'm using udev, so I have no /proc/bus/i2c, 
but /sys/bus/i2c

I don't know what to do next...
It seems like I don't have a valid sensors.conf file, but, don't know 
how to build a valid one.

I hope this don't disturb too much to you. Thanks in advance
