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=20 and I can see battery levels, fan temperature etc. Bug cpufreq says at=20 boot that it can't find any cpus supporting acpi performance management,=20 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=20 more slowly by slowing down the cpu? Below is attached some printings from my proc directory, but i really=20 have no idea where to start, any pointers will be appriceated.
