Looks like this functionality is even more broken than I thought. Upon disabling and re-enabling "reduce backlight brightness" in the "On Battery Power" tab of Power Management Preferences, I'm receiving a whole host of funny effects when I try and change my brightness manually with the fn keys. It looks as if the power management subsystem is bogged down or running extremely slowly. Changes to the brightness are not immediately applied and the brightness will sometimes change long after I've pressed any keys. Further, the applet displays an empty battery icon saying that it could not read the status of the battery for long stretches of time. Eventually, it will show the proper status, but only one or two minutes after the power state has changed, and even then it is not reliable. Currently, my laptop reads that it is plugged in when it is not, and it is set to minimum brightness.
