Using the '3D' hardware needn't entail dealing with DRI.  The MGA driver 
does precisely that for Render acceleration.

It might be of some use; applications can specify this operation through 
Render with a single-pixel tiled 'mask' operand to composite, but it 
won't speed up text or geometric operations at all.
