You are missing the kernel module for the Radeon. SuSE didn't include this, but they have packages for you. See my post here
You are probably going to have to uninstall those ATI drivers before going through this. Don't use Yast or sax to configure display devices! Use Yast only for package management, and I still haven't found a good use for sax. Follow the directions in my post and 3d acceleration will be working.
