And that is the correct fix. Horrible hacks to avoid the version check will not
be committed, the check is there for a reason. Just stick with xorg-server 1.2
until ati releases a version that works with 1.3.

I'm afraid you're out of luck. If you have one of those cards you will have to
use the opensource drivers or stick with xorg-server 1.2.
