After commenting out code in the i2c-piix4 code to stop it from loading the 
driver I noticed the following odd results:

It appears the IBM has a lm80 chip.

The 'odd' thing is it reports i2c devices?

There are two fans on this board. the PSU fan and a special case/cpu fan which 
only turns on when the CPU is getting hot it is usually off if the machine is 
idle.
