(Note there was a report that "," is missing before the ofwboot.xcf path)

I've tried it on My Power Mac G4, then it needs more tweaks:

The ISO9660/HFS hybrid install ISO contains Apple partition map
and the second entry for NetBSD_bootloader is marked as bootable,
so maybe we have to explicitly specify the third partition as
an HFS (as ISO9660 hybrid) partition where ofwboot.xcf is stored.
