On desktop systems, nothing other than ondemand ever makes sense. 
There's already a kernel knob for setting maximum latency, but right now 
I believe it only takes C states into account. You're guaranteed to get 
code running within that window, it just makes no guarantees about what 
speed the CPU will be running at or how long it'll take to ramp up.
