Bug Description
******* Problem *********
Toshiba Satellite P100 PSP-A3C laptop, Nvidia GeForce Go 7600, running Karmic 2.6.31-15, Nvidia proprietary driver 185.
GNOME-Sensors applet reports CPU stable at about 60 C, GPU climbs slowly up to about 90 C, then the system shuts down.
On 9.04, I had the same problem, but I was able to load a custom DSDT, after which the fan ran properly, and the system stayed cool, GPU around 65 C. Also stays cool under Windows XP.
I understand that it is not possible to load a custom DSDT under karmic, so I need another solution.
******** Possible Fix **********
After some more hacking in DSDT, Yann found that fan control is located in ACPI EC (embedded controller) address space : VTMP acpi byte in acpi EC bit field, at offest 0x5E.
Yann found some similar concerns on some acer laptops (having the same WMI related acpi methods, located in device AMW0), and with a perl script that Yann was able to modify in order to setup a constant fan speed. That perl script is attached to this report.

Confirm the same issue here. My laptop is HP Pavilion dv5162ea. NVIDIA GeForce Go 7400, running openSUSE 11.2 with proprietary driver 190.42.
CPU temperature climbs up fast from 24C to 50C in just 15 minutes. Programs running are Opera, ChoqoK, pidgin, and JDownloader.
Prior to openSUSE 11.2, I was running openSUSE 11.1 and the temperature was stable around 65C. Never had to load a custom DSDT.
