Hello! I did some tests. I know eeePC-701 (celeron) was downclocked from 900MHz to 630MHz by asus engineers. If I don't "make" the cpufreq module at all in kernel, /proc/cpuinfo shows current clock: 630MHz I also did a small "stress" c program. time ./stress user 0m27.411s Now if I just load the cpufreq driver in kernel (p4-clockmod)+governors, when I boot I see "performance" governor is loaded. And cat /proc/cpuinfo shows 900Mhz clock. time ./stress user 0m27.414s SAME TIME! While if I do cpufreq-set -g userspace -f 630MHz it takes about 38 seconds !! so what I think is: cpufreq assumes the cpu is going 900MHz by default but it's false! it is 630 mhz ! Then downclock does a percentile downclock. so when i do cpufreq-set -f 630MHz cpufreq-set sets 70% of actual clock that is not 900->630MHz! BUT 630->441MHz that's why it's slower than w/o the module! (38s vs 27s) What do you think about it? I think is is something to be fixed. There's also an asus_eee.ko module out there (BTW it stopped working with 2.6.31), and it could "overclock" correctly.
