Squashed this into the fbconsole patch. Also I applied the patch I just
sent to the list which adds a fb_create_screen function which creates
a screen from a struct fb_info *. With this we get rid of the hardcoded
opening of /dev/fb0.
What's missing now is that fbc_set_active() should check the flags
argument and actually disable the fbconsole and free the resources.
Also I'm not sure if the framebuffer should be activated when the
framebuffer console is activated. While this is convenient for the
user we get into a reference counting problem. What if the framebuffer
was activated before the fbconsole? Should we skip enabling the
framebuffer in this case? When disabling the fbconsole then we must
now if the fbconsole code activated the framebuffer and only then
disable the framebuffer again.
