No, I don't think that is currently under development. Recent PReP
development has focusses on properly modelling the needed devices (e.g.,
pc87312).

There are patches around to add a new 40P PReP machine [1] but I don't
remember whether that was SMP-capable. The BeBox [2] has two processors
but our emulation attempts didn't get very far yet.

Andreas
