Changing a bunch of values in gconf-editor , solved this problem.

Changing the values for gnome power manager didn't really solve the problem , as I had mentioned before. I'm now using Icewm , without gnome-power-manager and the problem with the screen brightness still exists. I suppose this is a problem with acpi , rather than with gnome-power-manager.
