I think this is the same issue I'm experiencing. It's not just MacBook and not just after an obvious triggering event. It pops up when I'm on a/c as well as on battery. It usually appears when I first move the mouse after a few minutes of reading. And I do not have display dimming enabled on either a/c or battery. And I even went into gconf editor and unchecked the enable key for ambient brightness adjustments (which has been speculated in forums as the problem). Nothing I've tried works. I'm on a Toshiba Satellite laptop.
