But I do. :3

xf86-video-omapfb is just fbdev with a bit of hax to make Xv be 
semi-accelerated through the DSP. It's still massive amounts of fail.

IMO the correct answer is to port OMAP DSS2 to true KMS, and then add an 
SGX Gallium driver to make the SGX 3D core do acceleration, but that's a 
long ways off. (Unless anybody's working on SGX reverse-engineering, but 
my search so far has not indicated any progress on that front.)

As far as using the SGX/TI blob for acceleration, we only say, "Good 
luck." :3
