you may try 'true' also, if you don't get any screen output

Are you sure you are booting off a scsi hd ?
if not, 'ata/ata-disk@0:0' or similar could be the right thing

did you try 'screen' ?

I think you've got the wrong output-device settings ... and maybe the wrong
boot-device (not very helpful, I know...)
Unfortunately, this parameters are peculiar to your hardware.
If it boots another way (for example with floppy), look in /proc to see
if you have a device tree that looks like the paths in OF. I don't know
where it is exactly because that option is not built into my kernel, but
I _think_ it is in the default kernel.
If you find the tree, you may be able to see your devices and the correct
path to them (this should be under 'ata' for IDE hd, under 'scsi' for SCSI, and
your video card should be under 'bandit').
'dmesg' could also give you some information, at least about your video hw
You can also check http://www.apple.com (the support page) to find a detailled
description of your machine: all machines are archived somewhere (sorry for
the lack of detail). It may include a System Block Diagram that will show you
what hardware you have, and corresponding names (e.g. 'bandit' for the pci
