Ah no, that's not correct - BootX is an enhanced bootloader written by Apple to
enable multi-booting with MacOS X and grub-mkrescue is assuming that it is being
installed on a HD containing MacOS X with BootX in the default location. Whilst this
makes sense assuming that you are trying to fix booting a MacOS X partition in a
multi-boot setup, this certainly isn't the case for an installer CD. And certainly
this confuses things because in real life BootX is a COFF executable and not a
bootinfo file.

In my travels with qemu-system-ppc, most CDs I've seen use the CHRP convention of
\ppc\bootinfo.txt and then bless the \ppc folder so then no matter whether you are
using a Mac or other CHRP-compliant machine, everything boots the same way.
