Hi, I'm running 11.10 on the same Macbook model and also have this problem. When I resume from suspend, the screen is completely dimmed. I often can't see the login screen. The laptop screen also dims when I press Fn-F7 to change the multi-monitor mode. In both of these situations, I can bring the brightness back up with Fn-F2. But every time I resume or change monitor modes, it has to be done again. I found the problem resolved for the multi-monitor switch when I chose "Turn off after: Never" in the Screen options. However, the problem returned after another suspend and resume cycle.
