For now I've built a GLNVD enabled package set and uploaded them to 
their respective testing repositories. Packages are syncing to the 
mirrors. For example:

nvidia-x11-drv-367.35-1.glvnd.el5.elrepo.x86_64.rpm
nvidia-x11-drv-367.35-1.glvnd.el6.elrepo.x86_64.rpm
nvidia-x11-drv-367.35-1.glvnd.el7.elrepo.x86_64.rpm

As can be seen above, I've added .glvnd in the release string, which 
makes these packages a 'newer' version to yum/rpm.

Thus, to test simply enable the testing repo and update:

yum --enablerepo=elrepo-testing update nvidia-x11-drv\*

and yum should pull in the updated GLNVD package(s). Then restart Xorg 
and test.

Looking at the linked libs for any OpenGL application should now show it 
is linked against /usr/lib64/nvidia/libGLX.so.0 which is one of the new 
GLNVD libraries:

I've only tested using glxgears. Works as expected for me.

If anyone is able to test these builds, please report which distro/arch 
and what OpenGL apps you've tested with. Assuming there are no major 
issues, we could consider switching to GLNVD enabled packages for the 
next major Long-Lived release.

Thanks.
