OK, based on your responses I'm going to mark this as fixed. Thanks!

If you continue to have problems with unexpected behavior, that is a
separate issue, so please file a different bug report.

I've only tested it with 10.10 64Bit Live-DVD on Lenovo 3000 N200. The
Fn-Keys are working now but every key-press the brightness
increases/decreases by two steps. You can see the first step of
increase/decrease but shortly after (about 0.5 sec), it makes a second
step.

This bug has been fixed upstream since 2.6.34-rc6 by this commit:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=3143751ff51a163b77f7efd389043e038f3e008e

I've rebuilt the i915 module in 2.6.32 with the patch above and the
brightness keys are working again as expected. I've been using this for
almost a month already, no hiccups or whatsoever. That being said, I
hope that the Ubuntu kernel devs will backport the fix, which has been
available for about FOUR months now, as soon as possible. This bug is
really annoying but can be readily fixed. Thanks.
