This kind of approach is used by Sun in their SPARC Solaris ports, as the
"OpenBootPROM" implementation never got past a certain stage, instead they
have enough to find the disks, ethernet, load a filesystem, and then the
boot loader layers on top a more "compatible" OpenFirmware representation
which presents to the real OS.

The OF on Apple is a little better/more complete and of course the Genesi
OpenFirmware kicks it's ass even more :3
