Nouveau doesn't really do PCI ID lists, so you have to match to the
vendor ID, check that you're dealing with a video card and not some
other nvidia device. Then you can use something like
nouveau_device_open_existing and the struct that you get from that
contains "chipset" which can be used to determine what you have.

Far away from the primal instinct, the song seems to fade away, the
river get wider between your thoughts and the things we do and say.
