The "autodetecting" mentioned into the live-config man page refers to
the xserver-xorg script and not Xorg itself.
If the xorg-driver boot parameter is blank, the script tries to detect
the driver by looking at the PCI ID of the graphic card, see the code ([0]).
When it finds the PCI ID of the vbox graphic card, it wrongly assumes
that the vboxvideo driver is installed, which it may not be true.
Then it creates (or an already created configuration file is copied) a
file in /etc/X11/xorg.conf.d which basically forces X to load that driver.
If the package containing vboxvideo is not installed, obviously X does
exit because the driver listed into the configuration file is not installed.

Eugenio
