Fbdev mmaps the framebuffer to user space then the user space programs handles the drawing. If hardware acceleration is available then the new framebuffer system will export entrypoints to that too. the framebuffer subsystem is being rewritten right now so that fbcon can exist without vgacon and others. There is also a proposal for video extensions and integration of fbcon and dri. _ Philippine Linux Users Group.
