Well, besides the docking Duo's, the top-end Macs have always come with a
2-bus system. In the 68k world, this translates to the Quadra 950. The
internal and the external busses are 2 entirely separate systems, with up
to 7 nodes each. Can we have NetBSD use both an internal and an external
hard drive, or as this never come up? Granted this is a Quadra, so we
wouldn't have the need to use 2 different drivers, but I dunno if the
existense of 2 busses poses an inherent problem.

Just curious,
