I think NetBSD would really benefit from a way to reparent the console
device at runtime (I appreciate this comment does not directly help in
any way at this point :)

AFAIK X requires a wsdisplay to run on - which you don't seem to get
with a serial console. I wonder if it might be possible to run it on
genfb?

Those dmesg outputs are _so_ different, that something seems very much
off - can you get dmesg.boot from both cases?
