Hum. We just had this discussion on the fbdev mailing list. Its because
you can open /dev/fb more than once which is brain dead for several
reasons which was pointed out on the list. One thing. When /dev/fb is
opened it doesn't set the vc_mode to KD_GRAPHICS. If it did then you
couldn't VT switch which is not the case. You have to find away to find
out its usage count.
