You have a application running which uses the framebuffer device, then
suspend with that app running.  You'll have to restore the state of
the device _before_ restarting all the userspace proccesses, otherwise
the app will not be very happy.

As long as the app only interfaces with the framebuffer device and not
directly with the hardware it won't notice.

Well, mmap("/dev/fb") will just map the gfx cards memory into
the applications address space, so they _will_ interface with
the hardware.

The apps data will simply not show up on the screen until the
usermode helper finishes.

Whenever writing to the gfx memory before finishing the initialization
is harmless or not probably depends on the hardware, I'd better not
count on it ...
