The machine has two hw.setperf levels, which are reported back as
hw.cpuspeed 500 and 600. The actual CPU speeds are these:
mains power battery
setperf=100 600 MHz 400 MHz
setperf=0 500 MHz 333 MHz
On boot, hw.cpuspeed is set to some garbage number. Toggling
hw.setperf sets hw.cpuspeed to 500 or 600 then.
I'll poke around some more.
