I suspect that your problem is occuring when init attempts to start login on
ttye0, the mac video console. Try switching off that line in /etc/ttys,
switching on /dev/tty00 and/or /dev/tty01, and see if that works.

I don't quite know why this is like this, but it's probably related to the
video and adb subsystems not being correctly configured when you use a serial
console.
