Didn't you say it worked with PCI DMA? With BusType "PCI" and DmaMode != "None" it is using DMA. Though PCI DMA is slower than AGP DMA, in some cases even slower than no DMA at all. :-/ > but even without dma the > performance is much better than on savage DRI 1.0.

I'll commit my patch to Xorg CVS and see if I can get the via-agp issue resolved with the kernel people.
