Exactly. In fact we can be more specific -- the "Macintoshes" in
question are the old-fashioned NuBus-based 68k toaster boxes, not the
more recent designs with a PCI bus. Relevant stuff in the
Configure.help implies that MAC_SCC and MAC_SCSI enable support for
the on-board hardware built into those puppies.

You're really talking about a different issue here, autoconfiguration
rather than static dependencies. Giacomo Catenazzi is working on that.
