Just to close the loop.  We did briefly touch on this in the sync up call.  The basic consensus is that processor names are set by vendors, not by us as a project.  For commercial implementations, we'll take anything which is reasonable and supported by public material.  For non-commercial implementations, we may be stricter on naming - just to avoid polluting global namespace with designs which don't have wide adoption.  Basically, we'll revisit on a case by case basis as needed.
