And good luck doing that, because even if you do get it to boot into single
user (which you can do by typing ufs:/dev/ad4s1a at that mountroot> prompt),
you'll probably find that you don't have the entries in /dev for ad4, and you
won't be able to make them because / is mounted read-only and you won't be
able to mount it read-write because you don't have the entries for ad4 in /dev.

I used sysinstall to fix this when I had that problem, but it would have been
easier to swap the drive back onto the old IDE controller and make the devices
first.
