Larry, in practical terms for Linux and last time I checked
VBoxGuestAdditions.iso (5.0.17-106140), extracting VBoxGuestAdditions-
amd64.tar.bz2 the file init/vboxadd-x11 in line 423 got : 

           # Do not install if we can use the kernel driver.
            case `uname -r` in
                1.* | 2.* | 3.[0-9].* | 3.10.* ) ;; 
                * ) vboxvideo_src="" ;;
            esac

So it means for kernels bigger than 3.11 => vboxvideo_src="" and
vboxvideo_drv.so is not built. And is only used vboxvideo.ko ( # Do not
install if we can use the kernel driver. ) , RHEL7 got kernel 3.10 but
in 7.4 new kernel 3.10 have a backport of X stuff ... 

But for LTS versions like RHEL6, we may still need build
vboxvideo_drv.so , but hopefully also xorg-x11-server is minor than
1.17 .

Ah another new is that I added almost all work of Hans de Goede for
VirtualBox-guest-additions [1] in RPMFusion package [2] offering a
script to run apps through OpenGL passthru [3] "I've opted to go this
route rather then auto-enable at boot since OpenGL passthru has some
issues with some apps (and does not work when using gnome-shell + other
opengl apps on top)" . 
Also we got vboxvideo.ko in staging of kernel vanilla but not the other
kmod components yet, they are waiting for a review, if someone can
review it (the kernel patches) it will be great .
