I have found a solution to brightness changing if you have gone the
32bit route to solve the issues in this bug report.

In Kubuntu 11.04 32-bit, change to a virtual console, ie: alt+ctrl+F1,
change brightness with Fn+brightness to the desired level, then
alt+ctrl+F7 to get back to X and the level should be retained. This
isn't the most elegant but it is repeatable for my machine.

Also for what it is worth, it seems that other distros are not having
these problems. I have read reports of very happy slackware and Gentoo
users running 64bit gnome and KDE on the w520 with Discrete graphics. I
simply haven't had the chance to mess with trying something else yet.
