Modified Files:
      Tag: ati-4-0-1-branch
	Imakefile 
Log Message:
- Added kernel functions to initialize the driver, reset the drawing
  engine, wait for CCE idle and submit a buffer of CCE packets
- Modified the CCE packet dispatch mechanism to use a single submission
  function that can send the packets to the CCE in either PIO mode or
  using the ring buffer
- Moved CCE packet dispatch to the kernel driver
- Simplified the CCE macros and made them work with the new CCE packet
  dispatch mechanism
- Added an option to only allow legal/secure CCE packets
- Merged the os-support dir from the trunk into the ATI branch
- Fixed some of the engine hangs by reseting the engine when switching
  to non-CCE mode (Gareth Hughes)
- Fixed a bug where I wasn't grabbing HW lock around calls to
  WaitForIdle
- Fixed vertex buffer bug where it would wrap around and start reusing
  buffers that had yet to be processed (this is a temporary fix until
  vertex buffer allocation can be added to kernel driver)
- Added HW accel lines and points
- Added configuration support for selecting CCE mode, CCE security, AGP
  mode, AGP size, ring buffer size, and vertex buffers size in the
  "Device" section of XF86Config file
- Changed to map each region of AGP space separately (for security)
- Changed MMIO region mapping to be read-only (in secure mode)
- Fixed problem where swap buffers could be called when no back buffer
  exists
- Fixed resetting of the ring buffer in the client, X server and kernel
  drivers (also now correctly reinitialize the ring buffer read/write
  indices)
