I have physical access to the machine tomorrow or is there a way to check that
remote. Here is the sensors-detect output:

# sensors-detect
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 installed lm-sensors modules before you can use
some functions of this utility.
Also, you need to be `root', or at least have access to
the /dev/i2c[-/]* files for some 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.
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!
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-piix4' for device 00:07.3: Intel 82371AB PIIX4 ACPI
Probe succesfully concluded.
We will now try to load each adapter module in turn.
Load `i2c-piix4' (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: SMBus PIIX4 adapter at 5f00 (Non-I2C SMBus adapter)
Do you want to scan it? (YES/no/selectively):

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):

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 PIIX4 adapter at 5f00' (Non-I2C SMBus adapter)
Busdriver `i2c-piix4', I2C address 0x50
Chip `Serial EEPROM (PC-100 DIMM)' (confidence: 8)
* Bus `SMBus PIIX4 adapter at 5f00' (Non-I2C SMBus adapter)
Busdriver `i2c-piix4', I2C address 0x51
Chip `Serial EEPROM (PC-100 DIMM)' (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)? ISA
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, edit /etc/modules and add the modules
listed here to it:
#----cut here----
# I2C adapter drivers
i2c-piix4
# I2C chip drivers
eeprom
#----cut here----
Then, run /etc/init.d/modutils
To make the sensors modules behave correctly, add these lines to
/etc/modutils/local and run update-modules:
#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----cut here----
