NOTE!
Make sure you have the appropriate kernel modules loaded, such as cpufreq_powersave, cpufreq_userspace, and cpufreq_ondemand (see above note).
In Debian, all you have to do is:
# apt-get install cpufreqd
And in most cases it will work out of the box.
This is the default Debian config, but works well out of the box. Notice that the syntax for the config file has changed in cpufreqd-2.0.0, where you need to close [] sections with tags like [/Profile] or [/Rule].
