hi

hvae you had a look in /sys/devices/system/cpu/cpu0/cpufreq

it contains:

cpuinfo_max_freq  scaling_available_governors  scaling_driver    scaling_max_freq
cpuinfo_min_freq  scaling_cur_freq             scaling_governor  scaling_min_freq

my scaling_available_governors contains:

powersave userspace performance

and the command:

echo "powersave" > scaling_governor

lowers my cpu speed (as reported by cat /proc/cpuinfo ) from 1ghz to 667mhz on a ti powerbook.

i imagine something similar would work for you

ps should this be in a faq some where? should the be a menu in a gui to do this somewhere?
