Here you go..

Here is also the output of sensors-detect without lm85 or any other lm modules 
  loaded:

[root at typhoon ~]# 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.

  IF THIS IS AN IBM THINKPAD, PRESS CTRL-C NOW!
  IBM Thinkpads have a severely broken i2c/SMBus implementation, just scanning
  the bus will break your Thinkpad forever!
  If this is a non-Thinkpad IBM, we still suggest you press CTRL+C. We have
  had users reporting system breakage on other IBM systems as well.

  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):
[root at typhoon ~]# /etc/init.d/lm_sensors stop
Stopping lm_sensors:                                       [  OK  ]

  Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-i801' for device 00:1f.3: Intel ICH6
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 already loaded.

  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 c800

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.

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.

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

Driver `lm85' (should be inserted):
   Detects correctly:
   * Bus `SMBus I801 adapter at c800' (Algorithm unavailable)
     Busdriver `i2c-i801', I2C address 0x2e
     Chip `National Semiconductor LM85 or LM96000' (confidence: 7)

Driver `eeprom' (should be inserted):
   Detects correctly:
   * Bus `SMBus I801 adapter at c800' (Algorithm unavailable)
     Busdriver `i2c-i801', I2C address 0x50
     Chip `SPD EEPROM' (confidence: 8)
   * Bus `SMBus I801 adapter at c800' (Algorithm unavailable)
     Busdriver `i2c-i801', I2C address 0x51
     Chip `SPD EEPROM' (confidence: 8)
   * Bus `SMBus I801 adapter at c800' (Algorithm unavailable)
     Busdriver `i2c-i801', I2C address 0x52
     Chip `SPD EEPROM' (confidence: 8)
   * Bus `SMBus I801 adapter at c800' (Algorithm unavailable)
     Busdriver `i2c-i801', I2C address 0x53
     Chip `SPD EEPROM' (confidence: 8)


  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.conf:

#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----cut here----

To load everything that is needed, add this to some /etc/rc* file:

#----cut here----
# I2C adapter drivers
modprobe i2c-i801
# I2C chip drivers
modprobe lm85
modprobe eeprom
# sleep 2 # optional
/usr/bin/sensors -s # recommended
#----cut here----

WARNING! If you have some things built into your kernel, the list above
will contain too many modules. Skip the appropriate ones! You really should
try these commands right now to make sure everything is working properly.
Monitoring programs won't work until it's done.

Do you want to generate /etc/sysconfig/lm_sensors? (YES/no):
Copy prog/init/lm_sensors.init to /etc/rc.d/init.d/lm_sensors
for initialization at boot time.

The chip is pretty hard to locate on the board but if it's really necessary I 
can try again :(
