I do that via rc.local. Here is what I'm using on my laptop (i5-450M
based):

echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo ondemand > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor
echo ondemand > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor

echo "20" > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo "10" > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor
