In 11.10, the samsung-laptop module doesn't load, so controlling
backlight won't work just by mapping keycodes. If you follow the guide
from #7 comment you will have working kbd_backlight device in
/sys/devices/platform/samsung/leds/samsung::kbd_backlight/brightness.
However after you map kbdillumup / kbdillumdown keys, you still won't be
able to control backlight. There's some conflict when pressing
kbdillumup/down keys - keyboard input is broken after pressing. One
thing I've noticed is that if  you switch to terminal (ctrl+alt+f1)
after pressing the key, then switch back to desktop, keyboard input is
restored, the osd notification about keyboard backlight appears and
sometimes even keyboard brightness level changes (+/- 1 step). If
someone has an idea how to debug this situation (led device works
properly, keys are mapped in udev), please let me know.
