lxc-console simply proxying what it goes from container's tty.
Container's tty is, of course, in 80x25. I don't think that trying to
run framebuffer inside container is a good idea, most probably it will
fail. Use ssh =)

Yeap, there is such problem, but, at least for me, it still recieves
input, so I could just ctrl+D from it. That's not a big problem - best
idea is to use daemon mode
