 No error on your side.
 vboxvideo has switch to some vram helper code in drm.ko but I forgot
to add the files. I have no idea if it works as this wasn't tested but
you can patch with :
diff --git a/drm/Makefile b/drm/Makefile
index e9cee30de60c..e56b9343b94f 100644

 I'll do test over the weekend or early next week too.
