------- Additional Comments From [EMAIL PROTECTED] 2006-03-11 23:30 -------
The problem was that dev->agp_buffer_token was not set, and mach64 drm would
map the DMA buffers from linear address 0x0. With the one-liner below, it
correctly maps the DMA buffers from the same linear address as the vertex bufs.
I now plan to make mach64_dma_vertex use DMA buffers.
