Heh? So you are removing the check as to whether or not the async init
worked. Without the vma, fbdev doesn't exist and the hotplug event will
cause the machine to die (see recent history for examples). I think what
you intend is to always allocate a basic 1024x768 vma if the init config
finds no crtcs to setup.
