-1. Don't enable or map the brightness hotkeys in thinkpad-acpi, as
-   these older firmware versions unfortunately won't respect the hotkey
-   mask for brightness keys anyway, and always reacts to them.  This
-   usually work fine, unless X.org drivers are doing something to block
-   the BIOS.  In that case, use (3) below.  This is the default mode of
-   operation.
-
-2. Enable the hotkeys, but map them to something else that is NOT
-   KEY_BRIGHTNESS_UP/DOWN or any other keycode that would cause
-   userspace to try to change the backlight level, and use that as an
-   on-screen-display hint.
-
-3. IF AND ONLY IF X.org drivers find a way to block the firmware from
-   automatically changing the brightness, enable the hotkeys and map
-   them to KEY_BRIGHTNESS_UP and KEY_BRIGHTNESS_DOWN, and feed that to
-   something that calls xbacklight.  thinkpad-acpi will not be able to
-   change brightness in that case either, so you should disable its
-   backlight interface.

-For Lenovo models *with* ACPI backlight control:
-
-1. Load up ACPI video and use that.  ACPI video will report ACPI
-   events for brightness change keys.  Do not mess with thinkpad-acpi
-   defaults in this case.  thinkpad-acpi should not have anything to do
-   with backlight events in a scenario where ACPI video is loaded:
-   brightness hotkeys must be disabled, and the backlight interface is
-   to be kept disabled as well.  This is the default mode of operation.
-
-2. Do *NOT* load up ACPI video, enable the hotkeys in thinkpad-acpi,
-   and map them to KEY_BRIGHTNESS_UP and KEY_BRIGHTNESS_DOWN.  Process
-   these keys on userspace somehow (e.g. by calling xbacklight).

-   has been disabled.
