So, what do all of you think of the following implementation?

#1 The "policy modules" (/proc-interface, kernel-based frequency selector,
...) determine the target CPU frequency.

#2 This is then passed to the cpufreq core. There it is validated,
loops_per_jiffy and other values are adjusted.

#3 Then the cpufreq driver is called to actually set the CPU frequency.

#3 is absolutely ready, #2 in parts (the "policy module" interface is
missing, and the /proc-interface needs to be removed), and #1 is TBD.
