The thermal driver is working on my IBM ThinkPad T40 as well, btw. Nice to see you working on this!

Clearly, good end-user tools would convert to the preferred scale. That's obvious. So why kelvin? Simple. No negative numbers. Kelvin is an absolute-zero based temerature scale. Writing andything with ACPI means you don't have to deal with signed primitives. Integer as defined in ACPI means a uint32. nemo3383, I hope you had to look those conversions up.... :-) (I did last night) Temperatures reported (and used) by ACPI are all in tenths of degrees kelvin.
