It would be nice, though, to make this, or the smartdimmer/nvclock tool accessible using the keys. What do you think, would it be difficult and/or have a bad impact on the design of your package?
My packages do not handle brightness and brightness keys, since they are supposed to work out-of-the-box. So, I think you can safely bind the smartdimmer's commands to keys by using the utility 'compizconfig-settings-manager'.
Another question: Do you know abount any samsung with an nvidia chipset on which the brightness can be adjusted using your module?
No. Users have reported it to work on intel video cards and some ATI cards only.
Anyway, I suggest you to give a try to the 'nvidia-bl-dkms' kernel module found on this repository
