Re: [PATCH] acpi/video: Don't restore backlight to 0 at boot time

ACPI arguably does define 0 as being off (this is exceedingly poorly
defined), but I'm not entirely happy with this - the firmware makes its
behaviour conditional on the OS version. I'd really like to see an
updated version of the Intel opregion spec to get a better idea of what
we're meant to be doing here, but the last one made public was ancient.
