I haven't looked over your module, so I don't know if it contains any mistakes,
but this shouldn't be "defeating kernel security": it should map a framebuffer,
in which the kernel better not be storing any sensitive information (:-),
without making available the entirety of /dev/mem.  This is exactly what one
wants (after all, you could implement getpid() using /dev/mem ;-).
