I had a previous thread re Kernel 4.9.0 + Nvidia 375.26 (now stable).
I tried recompiling that kernel with DRM disabled,
& remerged Nvidia 375.26 , but X won't start.
Here are the last lines of  Xorg.0.log :

 (**) ModulePath set to "/usr/lib64/opengl/nvidia,/usr/lib64/xorg/modules"
 (II) The server relies on udev to provide the list of input devices.
 If no devices become available, reconfigure udev or disable AutoAddDevices.
