This is due to yaboot's ofboot.b script hanging if no display connection
is detected. See
for background.

Possible solutions:

* Using GRUB instead of yaboot?

* Removing the "screen" line from the ofboot.b script.

* Connecting something to a display output. With my G5, connecting just
a DVI-to-VGA adapter to a DVI port was enough to avoid the problem, no
actual monitor required.
