Yes, It can be removed.

- 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.
