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.
