Other than this, the information in that posting seems a bit overkill - the NVidia driver usually works very well without any SElinux jiggling.

+==== maintaining the NVidia driver ====
+The proprietary driver works well but it needs a bit of care. More to the point: parts of it need to be re-installed after kernel updates and updates of xorg-x11-* (both of which happen regularly).
+On RedHat systems that are regularly booted, the following lines in /etc/rc.local result in the necessary parts of the driver being re-installed automagically after booting:
+<code>
+ if [ ! -h /usr/lib/xorg/modules/extensions/libglx.so ]; then
+   echo "re-installing NVIDIA driver. This takes some time. Ignore any warnings."
+   /root/NVIDIA.run --no-network -s -n
