How do I change cpu governors?

EDIT: Sorry, my previous post was a rant. I have changed the title to reflect what I wanted to do.

Thanks to the posters below I now have cpu control.

a) It's best to just reuse the stock PKGBUILD for the kernel. It makes life easier. Just replace "yes
make config" with "make menuconfig" - also, make sure to change the pkgname and EXTRAVERSION so you don't clash with the stock kernel.
This makes life easier as pacman can manage/upgrade/remove your new kernel.

b) The scaling governor is controlled by sysfs. I'd recommend installing cpufrequtils and changing the settings in /etc/conf/d/cpufreq, then adding 'cpufreq' to the DAEMONS array in rc.conf.

I didn't bother compiling my own kernel and cpu scaling stuff works just fine for me. I just put

echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

in /etc/rc.local to set the governor to ondemand on each boot.

Solved.

Added speedstep_centrino, cpufreq_userspace and freq_table to /etc/rc.conf and used the command from my above post.

thanks guys.

btw.. the dudes on the irc channel are extremely rude.

Its kinda disheartening to see these members literally chewing out new users for asking a valid Q. Thats how distros get their false "elitist" status.There are always a few bad apples out of the bunch. It was the exact same thing with the gentoo irc channel.
