It seems that key codes are fine. This is what I get from 'keymap':
scan code: 0x97 key code: kbdillumdown
scan code: 0x96 key code: kbdillumup

Title:
Keyboard backlight does not work in Samsung Series 9 NP900X4C
Status in “udev” package in Ubuntu:
Incomplete
Bug description:
In Ubuntu 13.04, the keyboard backlight does not work in Samsung
Series 9 NP900X4C.
Adding the FN key mappings as described in
https://help.ubuntu.com/community/SamsungSeries9 does show information
in the notification area when pressing the keyboard backlight's + and
- buttons, but:
1) The notification always identifies the backlight as "full max"
2) It has no effect on the backlight - it's always off
When I first installed Ubuntu on this machine (12.10), even though the
fn keys never worked I did have intermitent backlight functionality -
the light sensor would sometimes work and I'd see light in the
keyboard.
I dual boot in Windows 8 and backlighting works there, so this is not
a hardware issue.
