What version of yaboot are you using? Something better than 1.2.1 I would think would have a better chance. You might try leaving out the comma if there's no partition number. I'm sure its needed if you put in the partition number, but I seem to remember in my experiments that it wasn't if you are not entering a partition number. Or OTOH cd:1,/vmlinux might be even better. One idea is to try to put yaboot on the cd also, I think by default it looks on the same drive from which it was booted. Which might allow you to just type /vmlinux. Another idea is to put a yaboot.conf with an image label on the CD too, then you'll be able to type the label.
