Might it make sense to do so in small, incremental steps that everyone can agree on as we go along? For example, maybe the very first thing to do is define some notion of general "operating point" that is a super-set of the cpufreq definition. If we can define that structure maybe we can progress towards introducing and using it. Totally side-step the kernel-user level stuff for a bit... Totally side-step the suspend/resume issues for a bit... Thanks, jdl
