What sort of graphics card are you using?  I'd guess it's an unsupported
one, and you'll have to use a serial console (ie, a separate terminal
plugged into the DB25 marked "3").  Look at the recent message from
Jonathan Stone below.

I'll have to add this to the FAQ...

Thats the best  guess, yes.
I would remove the serial terminal, put the keyboard back, and
boot to the PROM prompt (>>). Then do
	>> cnfg

and it'll tell you what the graphics card is. None of PMAG-C, PMAG-D,
PMAG-E, or PMAG-F are supported.  If you have one of tehse, do
	>> setenv console *

then plug in the terminal, remove the keyboard, and powercycle.  that
will automagically direct console I/O to the framebuffer when the
keyboard is in, and to the serial console otherwise.

9600, 8 bits, no parity, null-modem cable, the DB-25 next to the
reset button.
