cpufreqd 사용시 frequency 고정이 안 되네요.

데비안에 apt-get install cpufreqd 해서 cpufreqd를 깔았습니다.

IBM X40을 쓰고 있구요, 그래서 원래 최대 1300MHz까지 동작하는데 보통 땐 600MHz로 동작이 잘 되고, 컴파일하거나 cpu load가 높아지면 freqeuncy scaling이 잘 동작하는 것 같습니다. (gkrellm을 띄워놓고 보면...)

그런데 mplayer로 영화를 볼 때 1000MHz로 고정이 되도록 설정이 되어 있는데, 실제로는 그렇게 동작하질 않습니다.

계속 600MHz로 동작을 하다가 순간적으로 cpu 점유율이 동영상 재생으로 인해 높아질 때만 cpu frequency가 1200~1300 정도로 동작을 합니다.
그러다 재생 중임에도 불구하고 600MHz로 떨어지구요.

이와 관련된 문제를 겪으셨거나 해결하신 분 계신가요?

아래는 제 cpufreqd.conf 입니다. 구글에서 찾은 것을 가져다가 조금만 고쳐서 쓰고 있습니다.
