Can you test the mainline kernel to see if the issue exists upstream? You can see how to test it here: https://wiki.ubuntu.com/KernelTeam/MainlineBuilds

Also, does the brightness change with the brightness applet? Try adding the brightness applet to your panel and changing the brightness, so we can see if it is a backlight issue or a hotkey issue.
