Probably easier, yeah.

KVM supports embedded PowerPC (440 and e500 at the moment), and there
has been some work to port it to ppc64 cores like 970 (without using the
hardware extensions, since these are unavailable on shipping systems).
If you're interested, you should check out the trees at
http://powerkvm.org .

What hardware do you have available? Qemu has made great progress in
PowerPC target support in the last 6 months, and that can be very
convenient even when you have real hardware.
