Ah, OK, I think I have misunderstood you. So you already have a workaround with a xorg.conf file and everything works now, right? If that is the case, the only thing that needs to be done is to add your system into the video module's DMI table so that the acpi_video interface will not be created. This can be verified by adding video.use_native_backlight=1 to kernel cmdline.
