Well, it seems to depend on which way it's configured. It looks like VNC
with AMT enabled uses one port, without AMT uses the standard VNC port
(5900). I note that the former seems to exist, but the connection times out
(maybe disabled when not in the BIOS? - same with amtterm) and the latter
doesn't exist. This seems to offer a small window to get in when rebooting.
Rather clumsy to use, if you ask me.

I'm going to try connecting while doing a reboot.
