This is rather a hack to fix brightness hotkeys on a Clevo laptop. CADL is not used anywhere in the driver code at the moment, but it could be used in BIOS as is the case with the Clevo laptop.
The Clevo B7130 requires the CADL field to contain at least the ID of the LCD device. If this field is empty, the ACPI methods that are called on pressing brightness / display switching hotkeys will not trigger a notification. As a result, it appears as no hotkey has been pressed.
Not ideal, but definitely better than nothing.

Queued for -next, thanks for the patch.
Unfortunately this results in a neat black screen on my ivb zenbook. Until I've figured out what exactly's going on, I have to drop this from -next again. -Daniel
Can you share your acpidump on https://bugs.freedesktop.org/show_bug.cgi?id=45452 ?
Attached. -Daniel
Thank you, I've now written a partial analysis which is available at https://github.com/Lekensteyn/acpi- stuff/blob/HEAD/dsl/Asus_Zenbook_DanielVetter/analysis.txt (note: URL is cut in two parts in this mail, concat them as needed).
Question: can you try disabling the asus-laptop module and try booting again w/ and w/o the CADL patch applied? - Does it boot in both cases? - Do the brightness hotkeys work? - Can you change brightness via /sys/class/backlight?
Can you SSH in it and check the logs? Any ACPI warnings/errors or messages from the asus-laptop module? (or whatever asus module(s) is/are loaded)
Can you also generate dmidecode.txt? (peek in http://lekensteyn.nl/files/get- acpi-info.sh, you do not have to run all of the commands since I already have your acpidump)
Thanks, Peter
