I don't think we have any code that assumes anything about the PAT,
apart from WC being available (which seems like it should still be
the case with your modified PAT). I suppose you'll just have to
start digging from pgprot_writecombine()/noncached() and make sure
everything ends up using the correct PAT entry.
