On the long run I'd like to make the cpufreq governor a feature of the
cpupool. This would enable an administrator of a large Xen machine
with a heterogeneous load to specify which domains should run at
full speed and which are allowed to save energy at the cost of latency.

What do you think?
Certainly an interesting idea, with the question of how an implementation
of this would look like.

Let me do some research work first :-)
I hope to make a proposal soon.
