Brain fart alert, mine's a 7455. I should look at my dmesg output more  
often :o

I just looked at powerd and I don't see a way for it to control CPU  
speed, although you probably could put something in a sensor script to  
lower CPU speed if it gets too hot. Not that there's a guarantee that  
we have a CPU temperature sensor or that we have a way to match a  
sensor to a CPU.
IIRC there's a daemon to control speedstep on x86, maybe we should  
look at that instead of reinventing the wheel.

have fun
