This is just a wild suggestion, I know nothing about the code involved.

Would it be reasonable for the code that gets into DDB to get linked 
up with the display driver (if there is one on the box) and do something 
simple but conspicuous like video reversal to indicate that you are 
in DDB rather than hung? 

or play a tune on the keyboard or ...  Anything to provide a strong 
hint that will indicate that the system isn't really hung.
