i have compiled a few OpenBSD ppc kernels a few months back that load to
0xc0000000 or 0x90000000. i believe that i used objcopy to copy the sections
that i wanted into a xcoff file, and played with the ld.script too.

i didn't have any luck getting the firmware to load the kernels. i think that
it would be easier to use linux's booter instead of ofwboot since it could read
the powermac partition tables (and ext2), and that it works. i was doing some
work from powermac linux, hence the ext2.

i don't have access to my powermac linux box right now, so it'll be a few
weeks before i could play iwth this again.
