Instead of letting the user to determine whether framebuffer devices will be created (which is useless because they are gone by now), let's simplify the flow by allowing the user to choose between full, limited or disabled functionality. The determination happens only once, so, if the user decided to disable graphics support, the initialize method exits immediately. If limited functionality is chosen, then a generic DisplayConnector is initialized with the preset framebuffer resolution, if present, and then the initialize method exits. As a default, the code proceeds to initialize all drivers as usual.
