Hi hotKoffy, thank you for your brilliant work!!
I had edited my dsdt and tried your 1.2 kext out on my notebook Asus L50VN. Before the kext installation, its backlight levels can only be adjusted at the Chameleon greeting screen stage. The same settings can be kept exactly to the next boot-up, despite the disability of being changed dynamically in the OS X. After the kext installation, the backlight adjustment buttons on my Apple wireless keyboard really worked fine!! Both the AC/BAT start-up backlight levels can all be kept to the correct preset 0x08 in the dsdt. Everything seemed fine except one little problem: the backlight intensity did not change actually...
I checked the logs and the following errors can be found:
Nov 23 13:28:58.000 kernel: ACPIBacklightPanel: Found Backlight Device: LCDD
