So, this is really a "pseries" machine type fact rather than a ppc64
fact. Is there a way to make this dependent on machine type rather
than target architecture? Naming this based on machine type would
seem to better match the "pc" things these are based on ("pc" rather
than "i386" or "x86_64").

Maybe we need to add a qtest_get_machine_type().
