The closest thing I've ever seen was a steam-based hardware survey Valve released a couple of years ago. Even then, there were tens of thousands of Wine users playing Steam games.
How did you see that? I'm always looking for "Direct3D HAL" 3D cards, but I never saw anything like that there. Though I always paritipate in the survey if steam asks me too to get a few more Direct3D HALs in :-)
