A black "glxgears" window is a known issue which has been filed at:

    https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=195851

and upstream at:

    https://bugs.freedesktop.org/show_bug.cgi?id=6357 ,

where you can find a patch which allows to settle the issue. It is included
in the current "Xorg" development tree, so expect things to work better
in "Xorg" 7.2 which should make its appearance in "FC7".
Otherwise, a "Red Hat" fix for "FC6" applying the patch mentioned above is
pending according to "Bugzilla" #195851.
I have patched the "xorg-x11-drv-savage" driver package myself, and it
works very well now.
