This looks like a dupe of what's already in linuxppc-2.5.

This looks like it should be done in prxk.c, with the various hooks that
we provide in misc.c, which might have to be ported to misc-embedded.c.

Eh?  Is there more to come that moves 8xx towards what we have on
pmac/prep/chrp ?  Or a left-over from older kernels?
