This also happens in a Asus L3C laptop (Feisty, upgraded 5-02-2007). Altough if I change brightness via g-p-m-brightness-applet it will show the correct value in the tooltip, until I pop the scroll, which will always show at 0% and reset the tooltip to 0%. It still flickers badly when adjusting via the scroll. No problems setting brightness via Fn-F5/F6, though.
