Ok, got it up and running. The (very) good points:

- installed without a hitch (running Gentoo here);
- Dri working out-of-the-box (had to mess around with DRI cvs with older 
- RenderAccel accepted by my Radeon IGP 340M;
- No crashes so far, also with GLX+Composite+Transset+RenderAccel.

The "placebo" points:

- seems snappier;
- displaying of fonts on screen seems much faster. I tried to do "find /" on a 
console with aa fonts and seemed faster than prevoius version (is this 
because of RenderAccel?)

The not-so-good point:

- transparencies and shadows are still dead slow. Better with RenderAccel, but 
still quite unusable. Is this because the lack of support for component alpha 
rendering in the "radeon" driver? Is there something to tweak to get better 

Anyway, this seems to be going in the right direction. Amazing! Thanks to all 
the people who are working on this project, you are great! :)
