It'd be pretty awesome if someone would care enough to port this all properly to a class interface, perhaps submitting a command stream to the core via a sw object on PFIFO (emulating how EVO works basically, and also what nvidia have done forever..).. But, this seems unlikely given how old this hardware is now, so, lets just hide it away. There's a heap of other bits and pieces laying around that are still tangled. I'll (re)move them in pieces.
