GraphicsV drivers should make this call once they have completed their initialisation and are ready for use by the OS. Once this call has been made the driver should expect to receive requests on the GraphicsV vector.
Prior to making this call, OS_ScreenMode 64 should be used to request a driver ID from the system, and the driver must install itself on the GraphicsV vector.
When the driver is ready to shut down, it must call OS_ScreenMode 66, remove itself from GraphicsV, and then call OS_ScreenMode 67 to release the driver ID.
