> Hey, why not

The Nvidia and hypervisor restrictions you were already explained. Regarding SMP, as I said the dual-threaded PPE can be used with SMP but is probably not the best example to show its merits. Kronos probably refers to the fact that the Cell CPU as a whole (PPE+SPEs) is an asymmetric design, so the SPEs can't be used with SMP.

To quote myself: Only on models the required firmware version was originally released for, which means pre-slim models.

> Hypervisor is gogo

The hypervisor itself does not prevent MorphOS from running, but it prevents full access to the RSX GPU by OtherOS (as already explained to you).

It's also used in server blades, TV sets, video transcoding cards and probably several other things.

No, unless it also had no prevention of full GPU access by hypervisor and was still in production with OtherOS capability.
