Committed by: anholt

Update of /cvs/xserver/xserver/hw/kdrive/ati
In directory gabe:/tmp/cvs-serv12890/hw/kdrive/ati

Modified Files:
	ati_draw.c 
Log Message:
- Fix a segfault on VT switch with DRI.  Still dies due to cursor
  allocation troubles.
- Move the RemoveBlockAndWakeupHandlers to match
  RegisterBlockAndWakeupHandlers.
- Enable R100 trapezoid "acceleration" when DRI is working, so that it
  can be exposed and worked on.
