Newer Lenovo BIOSes support the standard ACPI backlight brightness interface (_BCM, _BQC, _BCL). It should be used instead of the native thinkpad backlight brightness control interface when possible. This patch disables the native brightness support in the driver by default when we detect that the standard ACPI interface is available. The local admin can still enable it using the module parameter "brightness_enable". Note that we need to detect the standard ACPI backlight interface only in boxes for which we would load the native backlight interface in the first place, and that no ThinkPad BIOS has _BCL but misses the other methods, so the detection routines can be really simple.
