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.
