Based mostly on NetBSD/prep at this time since the earlier mvme160x boards are pretty much PReP compliant. Later boards in the range diverge somewhat from the reference platform, hence the separate port. Still needs *lots* of bashing into shape, but at this time it will boot to multi-user over ethernet on an MVME1603-051.
