Well, the question is now why the PPC_ symbol starts to appear with the
supposedly slightly different processing order of the patch. I guess I
need to start digging deeply into the acpica vm for that :( I don't
think the patch  really fixes the problem, just changes enough to make
it disappear for some magic reason.
