That's a good idea. I'm tinkering with the idea that when an app
switches to KD_GRAPHICS that it lock out all other attempts to access
the framebuffer. I ran two copies of fbtest about 5 seconds apart and
the results were interesting.... :)
So using KD_TEXT/KD_GRAPHICS as the access control mechanism between
multiple applications and fbcon might be the way to go. It already
tells the console to not to write to the screen so it seems like a
natural extension of the concept.
