I've just sent Ed a refined diff for testing to make sure that we only
unbind vgacon if necessariy, but still unregister it (to make sure it
can't ever interfere with module unloading). If that checks out I'll
submit this as a real patch, otherwise we can go with Chris' slightly
bigger cannon.

In any case there seems to be a bigger dragon lurking since unbinding
the radeon fbcon really should kill the machine (but it can result in
a bit of a black screen, so checking that vgacon is bound is trtdt
nevertheless).
