Difficulty: finding "reasonable" defaults. But given the values, I

So even if cpu_running_mark were 100% (-r100), anything busier than 25%
of our example 75MHz would shift to maximum freq immediately, where the

(at -r100) needed to keep it at that freq; ie

Attached is a proposed patch for -head that adds a "hyper" mode to
powerd. Instead of slewing like the adaptive modes, this mode drops all
the way to the lowest frequency when the system is idle, and jumps all
the way to the highest frequency when there is any load.
