Yes, I have also this issue on Fujitsu E8420 BUT I have managed to get it working and wanted to publish my solution here.
Im running ubuntu 11.10 and I have installed that additional driver #2, NVIDIA accelerated graphics driver (post-release updates) (version 173-updates)

So This is what I did to get screen brightness buttons working:

I run "sudo nvidia-xconfig " to generate good xorg.conf file.
then I added this following line to there under device
"Option "RegistryDwords" "EnableBrightnessControl=1""
like this:

Section "Device"
    Identifier "Device0"
    Driver "nvidia"
    VendorName "NVIDIA Corporation"
    Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection

And I hava my xorg.conf as an attachment:
