 This has been broken for-fvcking-ever. I told macallan a while ago that
 the whole console and framebuffer stuff does not work. This is when I found
 it:

 And here is the diff for my kernel!

 This is really crappy. Please file a separate bug for the boot -c.
 Unfortunately I am using my box as a router and I cannot reboot it,
 but we clearly need to debug this.
