WAY too late, but I just want to share my success in getting ME to work with my 6870 CF at 5760x1080.
I haven't tried re-enabling the things I disabled, but this works:
1) create a ME profile in CCC with CF disabled.
2) download Racer_S' hack from here:
http://www.tocaedit.com/ (right hand side)
3) run the hack tool and keep it running.
4) fire up the game...in settings choose whatever res you want, turn off AA
5) start a game and hit the * key and then + and - ( / = disable)
here are the settings that seem good to me:

and here's what it looks like:
