At least the problem I reported earlier to this list regarding booting
a G4 system is related to the lua loader.

When installing the fourth loader, booting works, when installing
the lua loader, booting fails with the output given.

However, this is on a 32-bit PPC machine. Can't test on a 64-bit PPC
machine.
