Hi Karl,

I have the same chipset on my Asus Z8NA-D6 board and decided to look
into this. There seems to be a thermal sensor in this chipset and
following Intel's documentation I wrote a driver for it. You can
download it at:
http://khali.linux-fr.org/devel/misc/i5500_temp/
Generic installation instructions are available at:
http://khali.linux-fr.org/devel/misc/INSTALL
Unfortunately it turns out the driver doesn't work for me. It returns a
constant temperature of 36.5°C. I've tested on a few other systems at
work, with the same disappointing result. I have read the datasheet
again but can't find what I got wrong, if anything.
I'm still sharing my work, in case it works on other systems, or
someone looking at my code can figure out what I missed.

Nothing obvious afaics. Do you get reasonable values for the limits ?

Yes, I get the default limit values mentioned in the datasheet:
intel5500-pci-00a3
Adapter: PCI adapter
temp1: +36.5°C (high = +100.0°C, hyst = +90.0°C)
(crit = +110.0°C)
