I doubt it.  You might be able to disconnect the neutral side and stick 
an am-meter between it and the fixture and see how much current flows, 
or if a break/fuse pops.  On 2nd thought, I wouldn't know how to 
interpret the results and you might damage yourself or the wiring.

You can supposedly hook up a GFCI breaker to protect a 2-wire circuit, 
but I don't know details on how to do it.
