An update on this bug... I have two raring installs. For one of them the brightness controls work, one doesn't.

The one that doesn't work is a vanilla upgrade to Raring 13.04 from Quantal 12.10.

The one that works is also an upgrade from 12.10, but there are two major differences:
1. I installed Gnome Shell
2. I am running the Mir PPA

I have no idea which of the above might account for the brightness controls working, but installing Gnome shell should be harmless and it's not a bad desktop - so I'd recommend to try that. I don't recommend using the Mir PPA.

There is a question on Askubuntu that I provided the brightness settings you can use (manually) to work around the issue:
