For which there are neither bindings nor drivers.

Is anybody seriously proposing to hold back support for existing
(open source!) hardware in favour of an *imaginable* *possibly* better
solution? Especially when this exact line is already used in some other places?
(there's a space missing btw...)

I'm more than glad to follow any constructive improvements towards better
modularity. However there were none so far, and on top of that, it's a laptop.
I see little advantage in mentioning an internal connector when the panel
connected is always the same.

FWIW, Rob should also have received these patches.
