Ok, that really does reveal in how many locations we have conflated the
display generation and the render generation. I think the next step would
be a display generation enum. The third generation counter would be the
BIOS/chipset series. And then we have those promiscuous registers used
everywhere!

Reading through it, I think the render_gen patch just highlights the
obvious confusion and so we shouldn't apply it until we have some remedial
patches.
