Can you apply the following patch to include logo drawing support for all formats :-)?

It's not the switch back to text mode, that's very doable (see my other
reply). It's during give_up_console() at fbcon module exit. At this
point, the console suddenly disappears and freezes the system. Maybe we
can save the global "conswitchp" during fbcon module init, then
something like this at fbcon module exit:
void __exit fb_console_exit(void)
{
give_up_console(&fbcon);
take_over_console(saved_conswitchp, ...);
}
Is this feasible?
