I don't know if this helps anyone, but I tried to downgrade back to current Gutsy's version 6.6.193-1ubuntu1, but that version didn't understand my new dual head setup and I ended up in cloned single monitor mode. I then went to the 6.7.192-1ubuntu1 from http://people.ubuntu.com/~bryce/Testing/ati/ and it's working like was the Timo's 6.7.192-1ubuntu2.
