Update the DRM to latest from DRI CVS. This is approximately the version
included in XFree86 4.3, but includes some fixes. Notable changes include
Radeon 8500-9100 support, PCI Radeon/Rage 128 support, transform & lighting
support for Radeons, and vblank syncing support for r128, radeon, and mga.
The gamma driver was removed due to lack of any users.
