Well, we do give you a way out: do not load ACPI video, and load thinkpad-acpi with the proper parameters to enable its backlight control (if it is getting disabled by default). Check the docs.

Your X is broken, and in an extremely hideous way. You could try to get it to disable ACPI key support, or you can make sure nothing EVER sends ACPI video events to it. That means you must not use the ACPI video module in your kernel until you install a fixed X.org.
