The issue is that this ramdisk's inittab is not configured to show a
prompt on ttyLv0, that's why no more output there. The login-prompt will
only be on tty0 (e.g. the framebuffer).

allow_cli is not valid anymore with any recent version.
The easiest way to use X is to configure X for the fbdev driver so it
uses the framebuffer.
