I recently tried the mvme2307 (which is PreP).
IIRC I had to fix and hack quite a few things (in qemu)
to get it to boot but gave up after it seemed that
the OpenPIC didn't work out of the box.
Could probably be hacked, too w/o too much effort
but I ran out of time.

IMO it would be useful to be able to use qemu
but we should not abandon PSIM. The latter does
have (quite buggy but I have filed a patch fixing
many things) ALTIVEC emulation which qemu
unfortunately lacks.

OTOH the networking support of qemu is far
