Ok, I suspect that we need to enable reporting of events from them by some ACPI
video call; and that we will then get events for them on the "Video Bus" input
device.
I need to do a deep dive into your acpidump to see if I can find anything
there. Mondays are my "look into odd bugs which need more then a quick 5 minute
bugzilla reply" day, so I hope to make some time to look into this next Monday.
In the mean time I have one last 5 minutes idea :) Let me attach another patch
with some video-bus debugging added.
