Hello, 

in VBoxGuestAdditions_5.0.17-106140.iso, ./VBoxGuestAdditions-
amd64.tar.bz2, file init/vboxadd-x11, line 423 we 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 for kernels bigger than 3.11 (we are in 4.4), 
/usr/lib64/xorg/modules/drivers/vboxvideo_drv.so is deleted 
and not vboxvideo.ko, sorry about my mistake in my previous email.

Guest Additions update for Linux guests => delete vboxvideo.so and
vboxvideo_drv.so

diff listoldguestfiles listnewguestfiles -up 
+/usr/lib64/VBoxEGL.so
-/usr/lib64/dri/vboxvideo_dri.so
-/usr/lib64/xorg/modules/drivers/vboxvideo_drv.so

we still need kmod vboxvideo.ko 

btw also 
# New guest additions dropped vboxvideo_dri.so
#install -d %{buildroot}%{_libdir}/dri
#ln -sf ../VBoxOGL.so %{buildroot}%{_libdir}/dri/vboxvideo_dri.so

As is based on official vboc guest scripts you should try it IMHO.
