GRUB2 adds powerpc support
I've just uploaded version 0.6+20040429-1 of grub2 to experimental, which
adds support for powerpc.
Note that the code is highly experimental. It was written by Marco Gerards
in upstream and only reported to work on his computer. Feel free to have
a look and hack it up.

thing made, and neither in possession nor in his own mastery; wherefore he
gives and hoards not, and is free from care, passing ever on to some new work."
