Debian Sarge on IBM X40 howto - Part 5: CPU frequency scaling23 Jul 2004
This was quite easy:
apt-get install cpufreqd apt-get install gnome-cpufreq-applet
Finally add the applet to the GNOME panel.
Make sure that the acpi module is loaded in order to get cpufreqd to run, because without cpufreqd no frequency scaling will happen.
Now when ever you pull the power for your laptop the frequency will be scaled down to 66% until the system requires the recources. This can be cunfigured in /etv/cpufreqd.conf.
