David,
On most new motherboards are diagnostics chips that provide for a lot more than just temperature. Namely these chips are the National Semiconductor LM78, and LM79. The Beowulf project has a driver that I haven't evaluated yet for the LM chips. I too would like to see kernel support for all the features of the LM chips - both temperature, and fan monitoring, with adjustable alarm points, and a proc interface. Here is the Beowulf stuff, and National Semiconductor's application notes:
(I would also like to write a UPS daemon that monitors the LM chip proc interface, and a UPS/battery for a single combined shutdown daemon for laptops or desktops)
