I am not sure if the nightly tarballs work again (they have been broken since September), but there have been no changes to the MtxOrb driver anyway.
Depending on your firmware version it may not support the adjustable backlight like my LCD2025. You may try the attached patch to see if your display is affected (this patch actually disables the adjustable backlight and restores previous behaviour).
@Ethan: As you already mentioned this feature is not detectable by software and that you have an idea how to solve this. Did you made any advance?
