Do we actually try to handle non-primary planes in this function? If
I'm following this properly, at bootup we won't add any sprite or cursor
planes here, even though it's possible that a graphics firmware has
turned some of them on. It seems like our sw and hw states will still
be a bit inconsistent in that case.
