Is there anything wscons can do to help?
   	Given it is supposed to me the console driver of choice across
   	ports it would be nice to have a MI solution for this :)


not particularly, as far as i'm aware.  any solution would already
be MI, not sparc specific, as it would be in sys/kern/tty.c (where
TIOCCONS is handled).

there is already one hack in the kernel that hard codes the path
"/dev/console" -- the check to make sure it exists, and warn if it
does not.  this is purely something to help people who otherwise
will get a 'hung' machine.

i am investigating this issue again.  perhaps things have changed in
that many years ... :)
