Why do you prefer such daemon instead of leaving that to the kernel to
handle?  I notice the debian laptop task install cpufrequtils, and it
will feed values into /sys/devices/system/cpu/cpu0/cpufreq/* to enable
power saving mode when there is little to do.

This problem is still present.  Are there any packages able to detect
and install the correct cpufreq kernel module present in Etch or
available from somewhere else?
