Well, that got to the bottom of that.

I don't believe there is a bug in the elrepo packaging of the nvidia 
drivers, but rather for some reason nvidia-xconfig doesn't seem to 
recognise that you have X.org and thinks your X server is XFree86. That 
is why nvidia-xconfig has created /etc/X11/XF86Config instead of 
/etc/X11/xorg.conf (or did you manualy create this?)

Here's the relevant entry from the manpage:

The system X configuration file is found and read into memory. If no 
configuration file can be found, nvidia-xconfig generates one from 
scratch using default settings; in this case, nvidia-xconfig  will 
automatically determine the name of the X configuration file to create: 
/etc/X11/xorg.conf if the X server in use is X.org or 
/etc/X11/XF86Config if the X server in use is XFree86.

The elrepo package, in the %post install script, checks for the 
existence of  /etc/X11/xorg.conf and if it exists then backs it up as 
/etc/X11/xorg.conf.elreposave. We then run nvidia-xconfig to generate a 
new clean default /etc/X11/xorg.conf file. In your case it does look 
like nvidia-xconfig generated /etc/X11/XF86Config instead.

If you can demonstrate this behaviour on a new clean install of SL6 
(with a fully functional X Server installed) then you have a case to 
report a bug.
