Let me amplify on this a little.  As I understand it, Linus has decreed
that readb/writeb/(etc) shall work on busses which `look like PCI'.
All other busses (zorro, podule, sbus, ...) shall define their own
*_readb/writeb/...  functions.  People have proposed auto-detecting which
bus is being written to and doing the right thing, but Linus disagrees.
So that's why we have gsc_readb, because GSC looks insufficiently
like PCI.  Does this make sense?
