When Fn+F7 is broken

I already wrote that my OS upgrade broke the functionality of the brightness control keys on my ThinkPad (T60p). Brightness control is not the only thing that's broken. For instance, I cannot use Fn+F7 to project the display to a different device. The scripts available at ThinkWiki work well. To switch display to the externally connected projector, I just type:

sudo /etc/acpi/ati-toggle.sh

Not really very convenient to use; but I can live with this. Maybe I can rewrite this in C to use setuid bit (like I did for fixing the brightness control); since I don't have to project very often, I think I will manage with this script. Thanks to ThinkWiki guys!
