Have you built devices?

At any rate, though, this is probably not the problem.  The problem is 
the /etc/ttys has a line in it that tells the kernel to exec getty on 
your console (i.e. ttye0) as it boots into single user.  You need to 
adjust a couple of lines.  Edit the line in /etc/ttys that has ttye0 on 
it and change the word "on" to "off".  Likewise, edit the line that has 
tty00 on it (for the modem port) or tty01 (for the printer port, I think) 
to say "on" instead of "off".  This will start a getty on the appropriate 
port and should avoid the problem you were having.

Later.
