I just took a shot in the dark.  I did nothing but add uart and
remove my change /etc/ttys (because I got the impression that the
current /etc/ttys would work if I added uart).  The problem here
is that I have no real idea how these pieces fit together.

I can certainly try it again by doing all three of the changes you
have listed (along with removing my /etc/ttys change).  I can start
on that right now.  Thanks.

We had a production-server which was crashing every 20 minutes with
CPU parity errors at the time, so I couldn't really work on this. So
I took the simple way out, and just recompiled the kernel so I could
get all "installworld" changes installed.
