Well... I'm no expert on the embedded CPUs but I believe the
userspace part can be handled by emulating the missing
parts (like the FPU).

The MMU part of the 405 is quite different though. It would
take quite some work to port the MOL MMU core (and there might
be a significant performance overhead since the 405 MMU is simpler
than an ordinary PowerPC MMU).
