vlock -a is supposed to lock all virtual consoles.  The -n makes it
create a new vt, so it'll work even from within a running X session and
it seems to block the ability to switch back to the X session until the
system is unlocked.  But -n also requires root privileges.  Might also
want to throw in a -s to temporarily disable alt-sysrq.
This can basically take the place of your current screen locker and
does a better job than even xscreensaver of locking out the system.
