The older versions of fglrx do not work with Xorg 1.6. There is a 
compatible fglrx driver available from the repos, I am using it with my 
Radeon HD 3200. But that driver does not support some (not very) older 
cards anymore.

If your card is not supported by the new fglrx driver, you can read here 
for some info on the ati/radeon driver:
https://help.ubuntu.com/community/RadeonDriver

Specifically the links at the bottom have some good info for xorg tweaks 
for the closed source driver.
