Does SDL use DRI, even for 2d graphics? My understanding was that DRI
was only for 3d stuff like OpenGL.

Unless something changed recently DRI is only for opengl acceleration. There is 
(was?) an opengl backend to SDL, glSDL (
http://icps.u-strasbg.fr/~marchesin/sdl/glsdl.html
). 
With this backend you get hardware accelerated alpha blits, and it's is fast has hell. 
However, I don't think this is included in the standard sdl distribution.

The "old" way of getting hardware acceleration in linux is to use DGA, which only works 
in fullscreen and which has other problems. It also doesn't accelerate alpha blits..
