here is my system dsdt file after applying the "brightness fix (haswell)" patch, full of errors
You are disassembling your DSDT incorrectly. And you're applying the patch to the wrong file (your GFX0 is clearly defined in an SSDT).
Haswell Brigthness Fix:
You will need to extract all DSDT/SSDT from Linux. Your GFX0 device is in one of the SSDTs not DSDT and to get a proper disassembly of your DSDT (and the SSDT that has GFX0) you will need all of them. They are available in /sys/firmware/acpi/tables and /sys/firmware/acpi/tables/dynamic.
Place all SSDT/DSDT in a single directory and use a recent build of iasl to disassemble:

Code:
cd "to directory where you placed all SSDT/DSDT"
iasl -da *.aml
Then search the resulting *.dsl so you know where GFX0 is defined.
Laptop repo: https://github.com/RehabMan/Laptop-DSDT-Patch
Apply: "Rename GFX0 to IGPU" (to both DSDT and the SSDT that has your GFX0 device)
Apply: "Brightness Fix (Haswell)" to SSDT with GFX0
install: https://github.com/RehabMan/OS-X-ACPI-Backlight
Place patched DSDT.aml in /Extra/dsdt.aml. Place patched SSDT in /Extra/ssdt-1.aml (assuming you have already generated SSDT.aml for CPU)
Result: Working brightness slider in SysPrefs->Displays (mapping of keyboard keys is a separate issue), possible LID sleep, and IGPU power management.
