I can certify that all that fanciness runs under wine like a dream - it has a few stub warnings etc but I ran your demo fine on ubuntu 10.10 x64 wit wine 1.3.26.

I do indeed like that demo and it runs smoothly on my ATI 4330 with wine and a lot of other stuff open. I don't know about a GMA 950 or similar but that was quite nice indeed. Thats some momentum in the quad engine you've got going it seems.
