I haven't tried this on FreeBSD, but several years ago I had to do some
single user work on an SCO OpenServer box in Texas.  I had the owner of the
machine start sshd in single user mode, then I could ssh into the system to
work.  The SCO box activates the network in single user.  FreeBSD would
probably require starting network services manually.
