-         The frame buffer device provides an abstraction for the graphics
-         hardware. It represents the frame buffer of some video hardware and
-         allows application software to access the graphics hardware through
-         a well-defined interface, so the software doesn't need to know
-         anything about the low-level (hardware register) stuff.
-
-         Frame buffer devices work identically across the different
-         architectures supported by Linux and make the implementation of
-         application programs easier and more portable; at this point, an X
-         server exists which uses the frame buffer device exclusively.
-         On several non-X86 architectures, the frame buffer device is the
-         only way to use the graphics hardware.
-
-         The device is accessed through special device nodes, usually located
-         in the /dev directory, i.e. /dev/fb*.
-
-         You need an utility program called fbset to make full use of frame
-         buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
-         and the Framebuffer-HOWTO at <http://www.tldp.org/docs.html#howto>
-         for more information.
-
-         Say Y here and to the driver for your graphics board below if you
-         are compiling a kernel for a non-x86 architecture.
-
-         If you are compiling for the x86 architecture, you can say Y if you
-         want to play with it, but it is not essential. Please note that
-         running graphical applications that directly touch the hardware
-         (e.g. an accelerated X server) and that are not frame buffer
-         device-aware may cause unexpected results. If unsure, say N.
