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. - Adrian Cox, AG Electronics ** Sent via the linuxppc-dev mail list.
