Subject: Re: missing acpi backlight bisected to 9661e92c10

Well, that all looks fine. And I also can't see any way that this commit
could cause the backlight not to appear - all it does is set the parent 
if it's present. There's no new path that could cause it to return 
early. Does reverting this patch really make things work?
