Initial hacked-up code for synchronous DMA of vertex buffers (disabled but
...
functional for both PCI and AGP). 16 KB descriptor table is created by
the drm and the handles stored in the device private structure.
Finish setup of AGP -- AGP registers are now initialized.
Fix up MMIO for PCI.

buffer aging.

Add agp texture region info to DRM. Also, use DMA* macros for DRM
...
emit_state functions. This ensures a wait_for_fifo for the MMIO writes.

Code restructuring to be more similar to the existing drivers.
...
Implementation of several functions to support the handling of DMA
buffers. The DMA emulation code is disabled because it segfaults when
trying to read the DMA buffer.
