The patch makes drmAddBufs/drmMapBufs can handle buffers in video memory none

Description Austin Yuan 2004-10-18 19:36:28 UTC 
Some chips can't use system memory as dma buffer(or vertex buffer),for pci
card,it will use video memory as dma/vertex buffer. But drmAddBufs/drmMapBufs
can't handle this case.

The attached patch adds a new buffer type DRM_FB_BUFFER. It works like
AGP memory but uses video memory.
