If you look about 2/3'rds of the way down in your Xorg.0.log (I think it's like line 529 or so, you'll see a series of "drmOpenDevice" calls which all return a -1. Since it can't find the device, drm is never initialized and no drm = on dri.
I have yet to figure out a solution. Haven't filed a bug report against libdrm2 'cause the dev's will probably tell me that since no one using the open source stuff is complaining, it's ATI's problem. It would be nice if ATI would take a look at it.
Good luck!
