Oh, this is bold.

I would like to see this work, but I would need to see it tested on a
bunch of machines before I trust it.

I guess you now have the acpi video backlight check, which is good, but
again, doesn't work for all devices.

And yeah, a whitelist is tough, especially as the vendor isn't working
with us at all, but I don't want to break machines that don't need this
driver (and there are some, although I thought the newest ones would not
need it, but that might be true.)

Hm, if you can figure out how to get the acpi-video thing working for
some machines properly, I'll support this kind of change.

thanks,
