cpufreq: No CPUs supporting ACPI performance management found

Please, help me, I'm getting crazy using this notebook with the fan running at highest level all the time.

I've got a no-name (FIC M285) taiwaneese notebook with a regular P4 CPU.
When I build a Linux 2.6.0-test3 kernel, it recognizes some acpi-stuff and I can see battery levels, fan temperature etc. Bug cpufreq says at boot that it can't find any cpus supporting acpi performance management, even though I am able to throttle the cpu manually.

Where shall I start? Is it possible for me to get this damn fan to run more slowly by slowing down the cpu?

Below is attached some printings from my proc directory, but i really have no idea where to start, any pointers will be appriceated.

Best Regards,

Stefan Görling
