I see all of the output from rc.d stuff, and the date at the end,
but I never see anything from getty.  while single-user, I can echo
stuff to /dev/console and /dev/tty00 fine, but echoing to /dev/tty02
doesn't show up.

I tried dropping into ddb to try to poke around from there, but that
just got me a stream of traps:

telnet> send bre

kernel: undefined instruction trap, code=0
fatal undefined instruction in supervisor mode
trap type=10, pc=0xe004fac7, tear=0x8086100, msr=0x9b

0xe00eb6bc is in cpu_Debugger(), 0xe004fac7 is in db_command_loop():

ok, so I guess the more important question for me is, do we need more
testing of those changes, or can I just check them in now?  :-)
