You could try to disable fast-writes and see if that helps. To do that, just remove the AGP_FAST_WRITE bit in the set_agp_mode() function call in the nVidia driver.

I disabled fastwrites on the BIOS and now it seems to work. In fact, even DMA seems to be working. Some interesting stuff:

1 - I tried GLTeapot. It seems it is drawing outside of its window when you move the window around. 2 - If DMA acc is enabled, not only it will draw outside its windows as it will also crash GLTeapot somewhere in MesaSoftwareRenderer::SwapBuffers().

Having this in minda, any ideas? How much of a performance boost is fatswrites?
