Ah, temp registers. That's good, since IIRC there were a few atempts
long ago in this place to add temperature monitoring, but none ever
ended up with something useful. Finally, that 0 in the cpuinfo could be
replaced with something meaningful ;-)
Motorola have recently revealed that you cannot enable both thermal and
decrementer interrupts simultaneously. In typical Motorola fashion, they
have published this hidden inside the manual for the 755, with a note
that it also applies to the 750.

I've posted patches for the temperature measurement a few times - all
you have to do is to use the correct bit numberings, rather than the
wrong ones that linger in the kernel headers like a bad cheese.
