All fail with the error "Xlib: extension > XFree86-DRI missing on display :0.0" (to be clear, this error occurred with the Nvidia-installed > drivers as well as with the rpms).

Have you tried doing "rpm -e --nodeps XFree86-Mesa-libGL-4.3.0-42"? The NVIDIA libGL.so files conflict with the default XFree86 ones, and if that RPM is installed, the default files are found instead of the NVidia provided ones.
