nvidia users: about the xorg-x11 update

[Jack Spaar]

If you used nvidia's installer for the 6106 driver, you will 
need to re-run the installer after the new xorg-x11 update.

After the xorg-x11 update, glxgears dropped from ~5200 fps to 1750 fps.
Re-running nvidia's installer patched things up again.

This is because nvidia's installer effectively replaces some GL libraries
with nvidia's accellerated version.  The xorg-x11 update re-installs the
un-accellerated GL libraries.  [My explanation is approximate.  So is my
understanding. ;) ]

I wish there was some rpm-savvy way for nvidia's installer to handle
this situation.]
