How many kilobytes does removing an unneeded SCSI driver save?

Your statement abut "significant amount of mess" is absurd.  I see it
as no different than attaching a "scsibus" to a "bha".

The point here is that:

	(1) MII is a real direct-config bus.

	(2) There can be multiple PHYs on an MII.

	(3) The same model of Ethernet card may have different PHYs
	    as time goes on.

	(4) Eventually we may see Ethernet cards that allow PHYs to be
	    swapped (via some daughter card).

	(5) We need a card-independent mechanism to find and configure
	    PHYs on an MII.  The autoconfiguration framework provides
	    the machinery.
