There was some console related work done recently by both me and someone
else so it's possible this is a -current related issue.  BUT as far as
I know if you remove the keyboard there is nothing that would stop the
machine from at least printing the PROM monitor's initial boot-up dialog
to the serial port A.  Even if the NVRAM settings are for "keyboard/screen"
if the machine has no keyboard attached it should convert on its own
to using the serial port.

Do you get this initial PROM-related dialog at all?
