Okay, the priority is raised.

I have non-NetBSD commitments that *have* to take precedence
for the next week, maybe two weeks.

Supporting serial consoles ``the right way'' with new-style config and
autoconfiguration implies significant rewrites of the serial driver.
NetBSD/pmax has two serial drivers: the dc7085 used in 3100s and
5k/200s, and the SCC driver used in everything else (i.e., IOASIC
machines).

It would help me focus my time (and debugging) if I knew which was
more in demand: serial consoles for 3100s and 5k/200s, or for IOASIC
machines.
