People are able to use keyboard backlight keys on Samsung Series 9 laptops: http://jablonskis.org/2011/fedora-16-linux-on-samsung-series-9-np900x3a/
However I couldn't make it work on Series 7 although the keycodes are the same.

Title:
  Hotkeys for adjust the keyboard-backlight don't work on Samsung 700Z3A

Status in “udev” package in Ubuntu:
  Confirmed

Bug description:
  What I expected to happen: using these shortcuts should change the
  keyboard backlight on Samsung 700Z3A (and possibly more models of this
  series).

  What happened instead: nothing.

  Keycodes are 0x97 and 0x96 so I think it should be something like
  this:

  0x97 keyboardbrightnessdown # Fn+F9
  0x96 keyboardbrightnessup # Fn+F10
