  	(WaitQueue2K), (SavagePreInit):
  	* programs/Xserver/hw/xfree86/drivers/savage/savage_driver.h:
  	- Shadow status update thresholds on Savage4 were reversed. Fixed now.
  	- Fixed cobIndex on Savage2K. It used only a 4K COB so far. Now we
  	  have full 128K.
  	- Program the shadow status thresholds correctly on Savage2K.
  	- Savage2K reports used entries in the queue in qword units instead
  	  of dwords. Fixed WaitQueue2K accordingly.
  	- Event counter 0 is in status word 2 instead of status word 1 on
  	  Savage2K. Fixed ShadowWait accordingly.
  	- Added a ShadowWaitQueue function that doesn't idle the engine
  	  all the time. This improves 3D animation smoothness with concurrent
  	  2D activity when shadow status is enabled.
