To get rid of our ugly hacks to start X via the bootoption "startx", we
decided to run grml-x on tty7/vt7 which is defined in the
.zprofile-file.
When the bootoption "startx" is given, we switch to tty7 (via
grml-autoconfig) where agetty automatically starts a grml-user
login-(z)-shell and grml-x is started.
