    Thanks for doing this.

    So... a bit of rationale. The keyboard does not really fit into the
    LED subsystem; LEDs are expected to be independent ("hdd led") and not
    a matrix of them.

    We do see various strange displays these days -- they commonly have
    rounded corners and holes in them. I'm not sure how that's currently
    supported, but I believe it is reasonable to view keyboard as a
    display with slightly weird placing of pixels.

    Plus, I'd really like to play tetris on one of those :-).

    So, would presenting them as auxdisplay be acceptable? Or are there
    better options?

    Best regards,
    Pavel
