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.
