I can't get my laptop Compaq CQ60-420US to scale the cpu frequency. I have followed the how-to from this forum but still no luck. I have checked that the frequency scales successfully in linux, the temperature there is 50 C idle. Also in linux the frequency scales are 1200, 1600 and 2000, very different from the ones indicated by the driver in FreeBSD. In my FreeBSD 7.4 install, the temperature stays in 54 C idle and the fan is always on at high speed (like a little vacuum). Any help appreciated.
