IIRC, it was related to having to use a more recent Xorg and MesaGL
for the latest changes to work.  As soon as the ports freeze is over,
I assume they would get merged in.

I'm also hoping to see support for DRI and Xv and even 3D in RV780
chipsets soon, esp. now that AMD has finally decided to release the
RV600/700 specs to the public:
