I've tried the hints of Przemysław Kochański with Lenovo 3000 N200
(Product-Name: 0769AC6).
Concerning paragraph 3: the outputs of all Fn-Keys (excepting the
brightness-Keys) are plausible and OK. The Brightness-Keys doesn't
generate any feedback, not even an "unknown" or something.
Should i coll
On Lenovo 3000 N200, I have to revoke the experiences of Ualpa and mientefuego,
that the brightness-keys would work until (or short after) loading GDM.
In my case, the brightness-keys stop working immediately when passing grub2 in
the boot-process.

[Karmic] Brightness fn keys lost functional
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.
