Hmm, missing word, did you mean "two i2c devices"?

Most things here sound like crap. I'd suggest you try and collect some
information about your IBM system to know which chipset it is supposed
to have. Also, don't forget to run "sensors -s" before running "sensors"
to make sure that the config file is used. Last, see in the BIOS if it
shows some sensors information. It could help to know what kind of
sensors we are looking for.

You could also check wether the first lm80's fans values match the
behavior of your physical fans (for exemple, make the CPU hot using
cpuburn, and see if fan2 shows a value when the real fan starts).

Hope it helps.
