There's a POWERMAC_G5 kernel configuration in sys/arch/macppc/conf so this
must have worked at some point, but last time I tried building that it had
apparently bit-rotted.  The 64-bit processors can't boot an unmodified 32 bit
kernel, the MMU (at least) is different, so that kernel would need to be
resurrected.
