Seems to work fine so long as there is a monitor attached at boot time.
If there isn't then the whole system goes into loud windfarm mode and is
a warm brick.
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.
