I apologize if this is a stupid question since I don't know all the
spufs and cell details...

Don't you still need to set that SPU side register, or does the
hypervisor do it?  What stops a partition from setting it itself
and override whatever hypervisor setting there is, thus breaking the
partition isolation, etc?
