Thanks to Rodrigo's work, simple-ccsm now has a switch to easily enable/disable Compiz.
On openSUSE 11.0 users will not have to fiddle with any commandline, hack scripts or xorg.conf to enable Compiz. AIGLX is enabled by default on all the supported hardwares, and as soon as ATI/NVIDIA drivers are installed via 1-click, so all that is required is launch simple-ccsm (Desktop Effects) application and enable compiz.
