Yes, bind ``chvt 1'' to an ACPI event. It's a real day saver. 

At least on laptops you might find Fn-<key> combinations that are not
used otherwise. But you can use anything that emits an ACPI event, of
course. Other than that, I guess you could let your screensaver call a
script to switch the VT when it activates and set it to a short
time-out.
