    It's ages sony_laptop doesn't change, it may be some other change in the
    acpi layer that causes this.

    How about the input layer? /proc/acpi/event is deprecated and you should
    not rely on that.
    But anyway, it's a Fn key issue, not backlight control itself, right?
    Can you change brightness echoing to the sysfs files directly?

    don't know, can you bisect it?

    can you attach dmesg output after loading sony_laptop with debug=1 and
    pressing the brightness keys?
