Yes, but that was on 32-bit PPC using the gcc toolchain. If I remember it correctly,
it worked on 64-bit PPC. So it was a 32-bit specific problem and I go some feedback
that the problem might be related to the old toolchain.

This time it is on 64-bit PPC using the clang tool chain. Since the Blackbird used
petitboot, I'm not sure if it is intended to work on that platform. Also not
sure on the Mac G5.

Best regards
