I don't know.  The identical command line works on x86-64, but I
don't know if it's correct.

BTW KVM PR now boots the firmware, but fails when it tries to boot our
(Fedora) guest kernel because of missing emulation of 'ldx':

[764597.404573] Couldn't emulate instruction 0x7fb6502a (op 31 xop 21)
[764597.404583] kvmppc_emulate_mmio: emulation failed (7fb6502a)
[768211.269020] Couldn't emulate instruction 0x7fb6502a (op 31 xop 21)
[768211.269029] kvmppc_emulate_mmio: emulation failed (7fb6502a)

I will try to see if I can fix this and submit a patch if I'm
successful.

Rich.
