I think this can be OK... maybe the problem here is only that we are not
taking down the backlight right now at that time.  It's OK if the video
is insane or stopped then if it comes back OK when the backlight would
(ie, on power button press).

I did some meddling about the Glamo GPIO thing that went around the
houses including into glamofb.c before I saw it seemed to be a problem
with lack of comms to jbt6k74 on resume, maybe I have defeated the
framebuffer blanking action temporarily in there and that's all that
needs solving here.
