xserver/hw/kdrive/ati ati_video.c,1.1,1.2

Committed by: anholt

Update of /cvs/xserver/xserver/hw/kdrive/ati
In directory gabe:/tmp/cvs-serv3142/hw/kdrive/ati

Modified Files:
	ati_video.c 
Log Message:
Add R200 XV support, and make R100 (hopefully) use linear filtering
instead of nearest.  Also, use RadeonSwitchTo3D instead of doing the
WAIT_UNTIL ourselves.
