It would, since the patch sets all these quirks to false on
nvidia/fglrx/newer Intels.

That's why the patch detects the driver dynamically and treats the
quirks db accordingly. Just in case it got lost in the flood, I'm
attaching it here again.

Just to repeat: I'm not trying to convince you to apply it upstream
(although I don't see anything actively wrong with doing so).  As I
said, it's a working bandaid for distros which want to release soon
with some good OOTB suspend/resume capabilities.
