I had S3 unichrome graphic card on my machine

When i checked it on windows it shows that it's size is 32mb. When i try to play some small games like neverball it always shows that their is no 3d capability on my card.

All games work well on my windows.I tried installing xf86-video-unichrome-0.2.6 drivers but nothing changed

I tried to install drivers from motherboard manufacturer site
