Cool, in hope that recent kernel release will solve some problems with my cheap hardware I have upgraded to Linux kernel 2.6.22 using Debian package in unstable and surprisingly DRI started working. Actually I did not hope that Linux will ever support 3D acceleration on my VIA UniChrome Pro on-board video card, but it seems to be working now. Tux goes down the mountains quite fast. I even was able to run FlightGear with 1024×768 resolution, FPS is 5-10, but it’s quite playable.
Still have problems. DRI is working only on the first screen. XV is not working at all. Wine cores when DirectX game is run. But, it’s a miracle that the drivers from experimental branch works that nice at all. So, now new video card is not critical for my tasks.
