Asus N551 brightness patch

hi, i'm trying to fix the brightness controls on my N551 laptop. i've applied the patch Brightness Fix (Haswell) taken from the git repository. as the docs report the patch have to be applied where the device with 0x00020000 address is so i found it on my ssdt5 file and patched that file. compilation went good and i've also included the acpibacklight.kext into the Clover kext folder. i've patched the dsdt for battery also and it works good with the acpibatterymanager.kext
i also made sure to include the dsdt and the modified ssdt5 into EFI/ACPI/patched folder, in the clover config i've told to drop the oem ssdt tables.
i'm here because the pnlf device don't show at all in ioreg, nor the brigthness control on monitor, even if i can see on the clover boot.log it load both the dsdt and ssdt5.
obviously i'm doing something wrong but can't guess what.

attached my unpatched Linux extracted acpi tables, that i've used with MaciASL to patch and compile

i'm using last available clover bootloader with 10.10.2 ,can post more file if needed.i use the intel 4600 gfx card patched with 9mb cursor and device id which work with acceleration and the nvidia is disabled
thanks for any advice
