I get similar results on a Dell Inspiron 6400, which is a very similar laptop.
I can adjust brightness manually by the method described with /proc/acpi/video/VID/LCD/brightness, or by moving the brightness-slider in power manager (running KDE). The hotkeys used to work in feisty, and as far as I can remember also in earlier versions of gutsy, but stopped working a few weeks ago. I'm sorry I can't remember which update broke it.
