Real-base will need to be moved for your box, which you probably
already know. I believe you can determine if your Mac can boot
CHRP-SCRIPT by entering

dev /packages ls

and I believe the package you are looking for is called "chrp-loader."
Without it, Open Firmware will probably attempt to boot with an xcoff
bootloader.
