I've just created a branch in my personal xserver git repository where reviewed GLX and DRI patches will land. My intention is to collect, review, and test server-side GLX and DRI patches. When I believe the tree is stable, I will send a pull request to keithp. My hope is that this will get some patches into the tree a little faster.
For people who would like to try out this branch, it is available at:
