Additional preparations are not needed, and the
next thing to do is install the kernel and the GLX
package from Nvidia:
rpm -i /tmp/NVIDIA_kernel-0.9-769.rh70-up.i3U

This leaves the manual entry of the correct server in
/etc/X11/XF86Config-4. The GLX-Module is already
entered in the case of Red Hat as standard, so all
you need do now in the section Device is to swap nv
