In 2006.0 and previous releases, the CPU frequency modules were detected using the cpufreq service. This was quite bad to do this in a service, since it performs detection and computes modules list at each boot, while it can be a one-time process (such as in the lm_sensors service).

So, I've written a cpufreq.pm module in DrakX, based on the initscript. It allows to detect required modules, and to write them in a /etc/modprobe.preload.d/cpufreq file.

It is used by harddrake and the installer. The plan is to drop modules detection from the cpufreq service, and maybe to remove this service, if nobody uses the syfs cpufreq initialization part.
