Wow, long bug. Hope I didn't miss something obvious. I have a Vaio VGN-CR120E with the " Integrated Graphics Chipset: Intel(R) 965GM" chip set and have always (since at least Hardy beta) been able to adjust the brightness with the following two command lines (although hotkeys have never worked):

sudo /etc/acpi/sonybright.sh up
sudo /etc/acpi/sonybright.sh down

Not sure how I discovered this workaround for the keys, but in release Hardy someone tipped me off that I could use the panel gnome-brightness-applet which gave me an acceptable solution. Unfortunately that is now broken in Intrepid and I'm back to terminal to adjust my screen brightness :-( https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/243904 ).

Anyway, hope this bit of information might be helpful to others.
