Olaf's suggestion to use netboot is a good one.

Have you tried googling "yaboot claim fail"?

I see suggetions to run yabootconfig, which normally
writes stuff to a special boot partition at /dev/sda1  
No clue how to do this for a CD.

The BSD faq has a long discussion

http://www.netbsd.org/Ports/macppc/faq.html#ofw-claim-failed

which seems to indicate that some load or offset is being
incorrectly specified.

There seem to be plenty of other discussions as well
