Sorry, but my confidence level on this one is very low.  We've had heaps
and heaps of Kconfig-related build errors in exactly this area.  I'd prefer
that a patch like this one have a lot of testing and review (and a
changelog?) before we let it near a tree.

Agreed, I can tell from what I've seen so far this will at least break
the PMAC users...

See my proposed patch, if that doesn't work, we should revert the
problematic change.
