You could use gnome-power-manager, which provides an applet that lets you
select clock frequencies or which scaling governor shall handle the frequency
Or you could add a line like
/usr/bin/echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
to /etc/rc.local to select a specific scaling governor on bootup. In this
case, the "ondemand" governor would be selected which adjusts the cpu
frequency according to need.
