Fedora Core 6 and AIGLX and KDE

How do you enable GLX under KDE? I looked in the xorg.conf file,
there's an entry under the section "Module" that reads Load "glx".
I checked in the KDE control center and found no way to enable this.
I can find absolutely no documentation on it except at redhat.com, where
they briefly explain what it is. Does this only work under GNOME?
I'm essentially trying to achieve all the video special affects, like
rotating desktops.


-Thanks
