Right, the RFC was mostly for discussing what to do in case commit 170269a9d3c0 does not work out well and ends up being reverted (as this was tried before and got reverted pretty quickly). I'll send a patch just removing all the entries for -next for now, and I'll try to remember that we need a patch like this RFC if we end up reverting.

When the windows8 related backlight problems became evident, 2 approaches were follow in paralellel, one was to stop claiming to be windows 8 / 2012, the other was to tell acpi_video to stop registering a backlight driver. I've read all the threads and it seems that which approach ended up being applied to which model laptop was never really a concious decision (AFAIK). So lets move all the models which are only on the win8 blacklist because of brightness issues to the use_native_backlight list, which is the smaller hammer to use to solve the backlight issues. Note: this is not tested on any of the affected models, this just seems like the sensible thing to do.
