CCE/CP requires the DRM, or something providing the same services as the
DRM does.  I'm working on that, through implementing the DRI for kdrive,
with the first step being a non-GLX but DRM-using ati driver.  I was
working on a DRM-using r128 driver, but now that there's "ati," I'll try
to merge it to ati and actually get it working (I realized what was
probably a bug this morning, now to go check...)

Also on the list is figuring out how to do xv using the 3d engine
(rather than overlays).  Lower on my list, but somebody ought to do it.
