------------------------------------------------------
Subject: vt: Delay the update of the visible console
From: David Hollister <david.hollister@xxxxxxx>
Delay the update of the visible framebuffer console until all other consoles
have been initialized in order to avoid losing information. This only seems
to be a problem with modules, not with built-in drivers.
