I haven't tried it, but is it possible to load this driver without recognized resolutions and graphic card? I have Intel HD, so it's not possible to run this card. I want to know is it worth of spending time :) No idea. This driver will load but I don't know if it will be used by AppleBacklightDisplay

New version 1.2: Added Boolean property in info.plist "BQC use index" to be use if your _BQC returns an index to _BCL entries (not tested)Added an optional DSDT optimization : you can add a method SAVE with same parameters than _BCM and on the same device in order to split the DSDT code that set the backlight value in the PWM control register (usually located in EC) and the DSDT code that save the value in CMOS (usually in the RTC second bank of RAM : OperationRegion (xxxx, SystemIO, 0x72, 0x02) but triggered by a SMI interrupt to ensure CMOS checksum computation)--------------------------------------------------------------------------------------------------------------- New version 1.1:Added : look at power supply status at start upCode correction : more checks on pointers and function return--------------------------------------------------------------------------------------------------------------- This is a driver for laptops which backlight are controlled by ACPI Methods:...
