If it fails, you can still get to a console.  The graphics drivers are
only used in X... just Ctrl+Alt+F1 (or F2,F3,F4...) to open a terminal
session.  F7 is your X session.

Often all you need to do if it fails is rename you xorg.conf  (mv
/etc/X11/xorg.conf /etc/X11/xorg.conf.bak) to clear the settings out
of it... X11 should properly detect the settings and work fine.
