Hello

I would like to ask whether there are any rules about context in which
functions from struct fb_ops are called, particularly whether they can
sleep and which functions may be called only between some fb_open
and fb_release (for example from fbcon).

I tried to get working two graphics cards using VGA arbiter patch
(http://www.ussg.iu.edu/hypermail/linux/kernel/0503.1/0054.html)
After some hacking it worked, but without proper locking.
