8 I use sys-power/cpufrequtils which is a commandline tool. It installs
9 "cpufreq-info" and "cpufreq-set". E.g. the command...

11 cpufreq-set -r -g conservative

13 will select the "conservative" power-governor. The "-r" tells it to set
14 all cores (which I assume you want). If you want to get fancy, you can
15 tweak acpid to call cpufreq-set when certain events happen; e.g. the
16 screen is folded down, AC power is (dis)connected, etc.
