I didn't know that Nvidia provided enough information to build a decent driver. How does its performance compare to their proprietary drivers?

I'd like to add a note about my negative comments on the Silicon Motion SM502. I've looked over Silicon Motions offerings and contacted their tech support. Considering that the company provides relatively complete documentation for their products, perhaps the choosing them isn't such a bad idea for alternative operating systems.

After reading about the struggle to get ATI's 4350 to provide just VGA output (with no 2D or 3D acceleration) under AOS 4.1, I can see the advantage of picking a company that is more forthcoming on the technical specifics of there products (even if their potential performance might be lower).

Being able to easily write a fully functional driver beats "potential performance" any day.
