I've thought before having running RTEMS on top of PS3 hypervisor, you
will need to port it to PPC64 and if you like using SPEs, then also add
all the needed SPE communication functionality and just after all this
hard work add a thin layer to glue the code to hypervisor. IIRC Sony's
hypervisor is there just to protect hardware from Sony unwanted access,
otherwise it should be a Cell based workstation with just a limited
amount of RAM. Please correct me if I'm wrong here.
