Oh and regarding testing...

qemu should help. For qemu ppc64, try -M pseries, that's fairly well
maintained since it's the basis for all our new KVM based products,
and there's still some (hopefully) working 32-bit mac stuff in there.

With pseries, I would expect that you can install fedora, debian or
ubuntu (in fact you can also install SLES11/RHEL6 I believe).

Cheers,
Ben.
