Well they came out with a couple chips below the 530 that kind of went nowhere but they do have linux drivers that sort of work. That 530 uses 25 watts to give about same graphics capability of nvidia and ati's low end offerings and it's doing it on HALF the power. One of those glued onto motherboard of mini-itx and you got a real live HTPC system that can run any video resolution with very good graphics horsepower. As long as you don't try to run windows with it VIA's 1500mhz cpu is plenty of cpu for linux.
Now double the the size of that chip to 128 bit with 2 or 3 of them in a mATX form factor and you got a megagraphicszilla that doesn't need pounds of aluminum and copper and 50 watts of fans to keep it from exploding.
This is not the virge though. This is the chrome s20 400 and 500 series and I think they only have drivers for the s20 series. Let me look around the GIT repositories. No that's ancient history stuff.
I think i finally tracked them down.
