That is so you can do things like use the physical memory address of the
framebuffer to display a image from a TV card into it. The frmaebuffer
itself is pretty safe to export to userland. MMIO can be tricker. The area
of graphics resource management is really complex. For now I'm just aiming
to get a clean seperation of the console system out of the framebuffer
layer. 


Personally I like to see the day when DRI and the fbdev layer are merged
but that will be awhile.
