I've tried twice now and I don't get an error message, it just goes to 
the main support ticket page and I don't get a ticket number and it 
does not show up in the list.

Here is the text of the ticket I was trying to submit:
I thought I submitted a ticket last night but apparently I screwed it 
up.  Forgive me if this is a repeat.

I installed i2c and lm sensors on a virgin redhat 7.2 box.  Took a 
little effort but everything compiled and installed.

I have a PCI form factor single board computer, the PCA-6180F from 
Advantech.  The manufacturer has confirmed they use a WinBond W83627HF 
chip for hardware monitoring.  Sensors-detect correctly identifies the 
chip.

  This program will help you to determine which I2C/SMBus modules you 
need to
  load to use lm_sensors most effectively.
  You need to have done a `make install', issued a `depmod -a' and made 
sure
  `/etc/conf.modules' (or `/etc/modules.conf') contains the appropriate
  module path before you can use some functions of this utility. Read
  doc/modules for more information.
  Also, you need to be `root', or at least have access to the 
/dev/i2c[-/]* files
  for some things. You can use prog/mkdev/mkdev.sh to create these /dev 
files
  if you do not have them already.
  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.

  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):
Probing for PCI bus adapters...
Use driver `i2c-i810' for device 00:02.0: Intel 82815 GMCH
Use driver `i2c-i801' for device 00:1f.3: Intel 82801BA ICH2
Probe succesfully concluded.

  We will now try to load each adapter module in turn.
Load `i2c-i810' (say NO if built into your kernel)? (YES/no):

Module loaded succesfully.
Load `i2c-i801' (say NO if built into your kernel)? (YES/no):
Module loaded succesfully.
  Do you now want to be prompted for non-detectable adapters? (yes/NO):
  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: I810/I815 I2C Adapter (Bit-shift algorithm)
Do you want to scan it? (YES/no/selectively):

Next adapter: I810/I815 DDC Adapter (Bit-shift algorithm)
Do you want to scan it? (YES/no/selectively):

Next adapter: SMBus I801 adapter at 5000 (Non-I2C SMBus adapter)
Do you want to scan it? (YES/no/selectively):
Can't open /dev/i2c[-/]2

  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.  Do you want to scan the ISA bus? (YES/no):
Probing for `National Semiconductor LM78'
   Trying address 0x0290... Failed!

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

Driver `w83781d' (should be inserted):
   Detects correctly:
   * ISA bus address 0x0290 (Busdriver `i2c-isa')
     Chip `Winbond W83627HF' (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)?

WARNING! If you have some things built into your kernel, the
below list will contain too many modules. Skip the appropriate ones!
To load everything that is needed, add this to some /etc/rc* file:

#----cut here----
# I2C adapter drivers
modprobe i2c-isa
# I2C chip drivers
modprobe w83781d
#----cut here----

To make the sensors modules behave correctly, add these lines to either
/etc/modules.conf or /etc/conf.modules:

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

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.
####End cut and paste of sensors-detect######

What I did:
Made the recommended edit to /etc/modules.conf
Added the recommended modprobes to /etc/rc.d/rc.local
copied the lm_sensors.init to /etc/rc.d/init.d/lm_sensors

After a reboot, I ran sensors.  No sensors detected.  The modules are 
loading just fine (lsmod shows the modules there).  I got an error 
about i2c-proc not being loaded so I added i2c-proc to the startup 
list.

##########End of output of lsmod##########

I'm confused.  The hardware can be recognized but apparently not 
communicated with.  I've tried a number of things just shooting in the 
dark:
manually run /prog/init/lm_sensors.init start (starts OK but takes a 
good solid minute for the w83781d to load)
manually edited the sensors.conf file to w83781d-isa-0290
tried directly calling sensors w83781d-isa-0290
tried browsing /proc (chip headers are there but no data)

the output of prog/dump/isadump 0x295 0x296
   WARNING! Running this program can cause system crashes, data loss and 
worse!
   I will probe address register 0x0295 and data register 0x0296.
   You have five seconds to reconsider and press CTRL-C!

Any idea what I am doing wrong?
