		implements double framebuffering by always calling display_write with
		a buffer equal in size to the connected panel.

		NOTE: when no framebuffers are allocated, the ELCDIF will be
		set to display an empty buffer during initialization. This means
		the display will show what is effectively a dump of
		system RAM until a new framebuffer is written. If the security
		implications of this concern you, leave at least one driver
		framebuffer enabled.
