Just adding the PCI IDs will most likely result in the driver trying to set up the card, failing because it’s newer hardware it doesn’t know how to handle, and leaving you with a black screen.
Well, I gave it a try and to no surprise it didn’t work. All I got was a quick trip to KDL. As I have no experience writing drivers of any kind this is where I stop. Unless someone else has the desire to work on it.
