Chances are good that ata-3 is secondary master, so ata-4 should be  
secondary slave.

I would try boot /pci@f2000000/@d/mac-io@7/ata-4/disk@0 in place of "cd"

And also, don't OF 3 machines need to boot from a Hybrid or HFS CD,  
not a pure ISO9660 disc? If you can't dir the device/partition then  
the firmware won't be able to boot it.
