cpufreqd is meant to be a replacement of the speedstep applet you can find on
some other OS, it monitors the system status and selects the most appropriate
CPU level.  It is fully configurable and easily extensible through the many
available plug-ins (more to come).
Despite its name it can be used to control also the NForce2-Atxp1 voltage
regulator and the core and memory clock for NVidia cards (see README.Debian).
You need a CPUFreq driver and either APM, ACPI (a recent version) or PMU
enabled in your kernel in order for this daemon to work.
