Sad that the daemon gone. It was able to dynamically switch speed
(and save power) on systems that have CPUs with high transition 
latency (e.g. old P4, some Atoms, etc.). On such systems the
ondemand governor cannot be used and if you want to save power
you need to change the freq from userspace (of course, not too 
frequently). It was not the best solution, but it worked, e.g.:
http://bugzilla.redhat.com/show_bug.cgi?id=697273
Is there any replacement?
