So far it looks like acpi_video attaches, but the lcd0 device is not active.
More interestingly, if you press brightness shortcuts, acpi_video can
see the brightness value change while screen does not actually change.
My conclusion based on bullshit and poking around in the acpidump, is
that possibly either:
1) We need to call some ACPI handle to put ACPI in charge of brightness
(google acpi brightness trapdoor)
2) acpi_video is attaching to the nvidia optimus hooks (yes, they're
there, I know we don't have that option) and is missing the IGD video
3) Something else is wrong with either acpi, acpi_video, or bios that is
preventing ACPI from working?
I am going to take more of a look tonight.
I think I can just hack in some ACPI calls straight to the ec if that
will work, which might also include the correct ones to resume the
display without KMS?
Calling some _ON function or something perhaps
