Your patch in general looks good.
But is renaming the config option from CONFIG_FB_CORE to CONFIG_VIDEO
the best choice?
CONFIG_VIDEO might be mixed up with multimedia/video-streaming.

Why not e.g. CONFIG_GRAPHICS_CORE?
I'm fine with CONFIG_VIDEO as well, but if someone has a better idea
we maybe should go with that instead now?
