The bare metal host and the powernv machine in QEMU do not use grub,
they use petitboot which parses all grub configs and supports quite a lot.

Using Linux for a boot loader is not powerpc-only thing really, some
folks do this too (forgot who, just heard this at the KVM forum).

I am not suggesting removing SLOF soon, and I'll probably add support
for "disk-label" later and this may be just enough for grub to boot from
a disk.
