I am still experiencing this problem. I have a sony vaio (I'm not sure which). My backlight Fn keys didn't work however entering
$ xrandr --output LVDS --set BACKLIGHT_CONTROL native (from bug #176888), allowed me to have control over my backlight. However while on battery, my screen brightness oscillates slowly. While on AC power, I don't experience this problem.
