Situation as follow: 2 GPUs + vesafb + kms. GPU 1 is primary, vesafb binds to it as fb0 radeon loads GPU 0 loads as fb1 GPU 1 loads, vesafb gets kicked off which causes fb0 to unbind console, which causes the dummy console to rebind. this means fbcon_deinit gets called, which calls fbcon_exit since the console isn't bound anymore and we set fbcon_has_exited. GPU 1 creates a new fb0 which is primary and we want to be console. fbcon_fb_registered gets called sets the primary up and calls set_con2fb_map, however as fbcon_has_exited is set nothing further ever happens. This patch bypasses the fbcon_has_exited and checks if the console is unbound, if its unbound it calls the fbcon_takeover which calls the vt layer to call the fbcon_startup method and everthing works.
