The "intel_backlight" kernel component has now landed in Oneiric (bug 568611), so this bug in gnome-settings-daemon is the only thing precluding proper brightness-keys controls for a wide range of laptops. Please apply this trivial patch to fix it.

Note that most backlight interfaces (which offer less than 20 levels) don't hit the bug so don't exhibit this problem.
