fbcon_switch has to be rewritten. I'm going threw the process of cleaning

It worked before. Strange. Do you mean for you console panning doesn't
work on the visiable VC or a non visible VC?

Yes!!! Of course there is the issue is the framebuffer that actual one
used for vgacon or is it independent, thinking multihead here.
