Fan control on ibook2

[Cedric Pradalier <cedric.pradalier@inrialpes.fr>]

Hi,
	I've noticed that the fan is started according to a much higher
temperature when using linux (2.6.3-ben2) w.r.t mac os x. (for instance
if I reboot on macosx after compiling my kernel, fan is started
immediately)

	Does somebody have a hints of what rules this ? Is there a parameter
somewhere, that can be changed ? Or does it corresponds to some kernel
or open firmware constants.

	Also. Temperature is always shown as uncalibrated in /proc/cpuinfo.
I've seen that this sentence is hard-coded. Is there a way to have it
calibrated ? 

thanks
