This seems awfully similar to Debian bug #570637. Please see if you
can contribute additional information.

On another issue, I notice that you're using lxfb as your console
driver. Please avoid it. The code hasn't been updated in ages and
there were various drawing issue left unresolved. Also, the driver
fails to understand the method used by GRUB2 to set the screen mode.
Instead, I'd recommend using vesafb.
