Hi, I have a dell latitude 6400 laptop with an intel 4500 mobile graphics card.
I suspect I have a similar problem, but it does not seem exactly the same, so I need to check with the bug reporter (Kees Cook).
When I resume the backlight is set to 0 (it is not switched off, 0 is the lowest value which let me see everything in the screen) and I can higher it using the special key FN+RIGHT_ARROW.
