[opensuse] Compaq nc6120 laptop: Overheating

Hi,
I am experiencing overheating problems with my Compaq nc6120 laptop. I have
installed opensuse 10.2 recently. Subjectively I noticed that the laptop is
getting hotter than usual (I previously used ubuntu 5.10 - kernel 2.6.12).
Under load (updating the distro with yast + running openoffice and a brower
sufficies) I get temperature shutdowns after a few minutes. It seems that in
termal zone 4 a critical temperature is reached (ie. more that 110 degrees
C).
I knew this phenomenon already from ubuntu 5.10 (and also from mandriva 2006).
Adding noapic and nolapic as boot parameters helped to tackle this problem.
With opensuse 10.2 (incl. all updates) this did not really change the problem
(although I subjectlively think that it now takes longer for the temperature
shutdown to occur).
I tried different combinations of boot parameters + updated the bios to the
most recent version. I also tried to exclude the acpi module fan from loading
(which was one of the hints I found on the web).
Using more recent kernels (from an opensuse repository) does not alter the
problem either!
The only "solution" up to now is to use the "energy saving" cpu throttling
(800 Mhz instead of 2.1 GhZ). Then laptop does not overheat, but it is of
course a lot slower.
On ubuntu 5.10 together with kernel 2.6.12 everthing still works smoothly
(without throttling the cpu down), so I suspect, that there is some kind of
misconfiguration problem on my side, or a bug in opensuse or more likely the
kernel.
What do you think? Many thanks in advance!
Best, Dominik
