At this point of time its not necessary, because still only one display is
supported (BTW: The 'bpp' value seems not display related, it a feature of
the framebuffer only).
But in future we need a solution for videomode and driver specific data. Maybe
we could add a private void pointer into the "struct fb_videomode" for this
When I release my "runtime videomode initialization" patch stack, we could
discuss where to store such special information.
