You could dig into it if you wish. if this is indeed the problem, you will have to figure out a way to maintain the state of the 3d enigne between the render accel and the DRI. you might want to ask Ian about it. you can also check the archives. there was some discussion about this in regards to using the 3d engine on radeon for Xv (YUV textures) and render accel. databooks were available, but I'm not sure they are giving them out anymore. Although I doubt you will really need them as the code is already there, you just need to make it play nice.
