That's all correct. The central issue is that the driver is not notified when the hot-keys are pressed. In fact, these keys don't even generate a scancode. Eventually, atimisc will provide its own key combinations to switch outputs under driver control. In the meantime, the laptop's outputs should be set up as needed before starting the X server.
