Thanks everyone, i've fixed my backlight problem with following steps:
1) set options video brightness_switch_enabled=0
to /etc/modprobe.d/video.conf
2) compile and install patched gnome-power-manager
Hope this changes will go to upstream. The only minor problem is that gnome-power-manager is not using libnotify's baloons similar to sound adjustment one, instead it spawns widget in bottom-middle of the screen.
