Now, do you have a frequency scaling governor running? If you do and you do something CPU intensive (say, bzip2 a large file, or compile a program or something), then you should see the frequency in /proc/cpuinfo, scaling_cur_freq, and scaling_setspeed change to the higher frequency while it is doing something. Afterwards, it will fall back down. If this works, then everything is okay and you will use your 3.06 GHz when you need it, and use less power at 1.6 Ghz when you don't. If you cannot seem to get it to go to the higher frequecy, try as root: cat scaling_max_freq > scaling_setspeed in the same directory as above. If you are then running at the higher frequency, then you probably do not have a governor installed. Perhaps try "yum install cpufreqd" or look around for another governor. I'm not sure what all is available for a Mobile P4. Jonathan PS. You need to add the mailing list to the To: addresses when responding, since I'm sending this directly to you as well.
