			MINI2440 configuration specification:

			0 - The attached screen is the 3.5" TFT

			1 - The attached screen is the 7" TFT

			2 - The VGA Shield is attached (1024x768)

			Leaving out the screen size parameter will not load

			the TFT driver, and the framebuffer will be left

			unconfigured.

			b - Enable backlight. The TFT backlight pin will be

			linked to the kernel VESA blanking code and a GPIO

			LED. This parameter is not necessary when using the

			VGA shield.

			c - Enable the s3c camera interface.

			t - Reserved for enabling touchscreen support. The

			touchscreen support is not enabled in the mainstream

			kernel as of 2.6.30, a preliminary port can be found

			in the "bleeding edge" mini2440 support kernel at
