There are a lot of different pci ids supported by nouveau, and more are
added all the time. The relevant distinguisher between drivers is the
chipset id.

I haven't tested this on real hardware yet, but perhaps this is a little less
hacky than the former version and will actually work for more than NV05. When
I test it out tonight, I'll add a print in there to make sure that it's
hitting the expected paths.
