The elrepo.org kmod-nvidia package already disables nouveau mode-setting 
(nouveau.modeset=0), blacklists the nouveau driver and runs 
nvidia-xconfig to create a suitable xorg.conf file.

Perhaps in the case of these hybrid systems we also need to blacklist 
the Intel driver too as suggested above. Do we know which Intel driver 
is being loaded?

Once you have worked out what works for you through testing, you should 
file a bug at http://elrepo.org/bugs/ and we can get these fixes 
incorporated into the package.
