Replying to [comment:26 mks]:
> To me it seems this depends on the driver used rather than the hardware
generation, i.e. the intel_extreme and s3 seem to work fine, but some
others, like the radeon_hd don't (yet?). Couldn't this possibly be enabled
on a per-driver base?
It's actually more hw-dependent. The reason being, a lot of the more 3D-
focused cards nowadays have almost nonexistent 2D acceleration, since it
mostly doesn't get used any more in the mainstream OSes thanks to
compositing. As a consequence, they can sometimes be slower at using 2D
acceleration hooks than by just using them as a straight frame buffer.
