Found a better way to disable hal's handling of the events
Instead of editing /usr/share/hal/fdi/information/10freedesktop/30-keymap-module-thinkpad-acpi.fdi
Simply add attached hal file to /etc/hal/fdi/information.
The file overrides the keymapping of thinkpad extra button.
I have deleted the sound volume events.
But you could easyli delete the brightness handling to.
This way the acpi daemon can handle the events, and launch the notification script!
