KWin and Compiz do not work identically. Some effects (eg. shadow) may look the same but the methods to achieve them can be different. I heard Compiz uses more OpenGL 1.x while KWin uses more OpenGL 2.x (though I can't verify whether that's true or not). So one method can be buggy on one driver while another method may work well.
That said, the radeon driver that ships with openSUSE 11.4 works fine in conjunction with KWin on my desktop PC at work.
Even before the upgrade from 11.3 to 11.4 we used SC 4.6 with KWin 4.6. Under openSUSE 11.3 it was sluggish at times with some effects (esp. the 'fade to gray' logout effect). Now under 11.4 it works very well.The KWin version didn't change ? 4.6.1 in both cases. The underlying operating system incl. Xorg and Mesa changed to newer versions.
Whatever distribution you're using: Switch to a more recent one that has newer Xorg and Mesa packages.
