In my laptop (MSI EX600 with Ubuntu Gutsy final) there is a similar behaviour - the brightness is adjusted automatically without an apparent reason - the screen can get dim or bright more or less randomly (actually it happened a few times while writing this message). Removing "Dim display when idle" option has no effect. When adjusting the brightness via keyboard, pressing a key combination (Fn+Increase of Decrease) can cause following actions: it can be no response, it can increase the brightness one step, or decrease it. The general direction of the adjustment is correct - if you press the relevant keys long enough, you'll get the screen bright or dim. In Feisty it worked more or less correctly, so it is a real regression.
