I have a PReP port for arch/powerpc that works for one machine, at
least. :)  The key part is the residual to device-tree converter that
I posted some time back with a request for people to test it on their
PReP machines, but I haven't heard back from anybody.  I'm going to
post the patch shortly anyway.

Paul.
