Not to say that /etc/X11/xorg.conf has been deprecated, but: The X11 "Quirks" files are a quick way to fix backlight control issues. I have smashed/replaced my LCD panel since reporting this bug, and no longer hear a buzzing noise when changing brightness while forcing the proprietary NVIDIA driver to control brightness.
For X11 quirk-related documentation, please read /usr/share/ubuntu- drivers-common/quirks/lenovo_thinkpad , and also https://wiki.ubuntu.com/X/Quirks . You can make a new quirk file that applies to your laptop. This sucks, but anyone can submit a patch. (Bad answer).
