I wanted to follow up to the list, as we've been debugging this offline, 
but we have solved the mystery, and the gpu hiding is working correctly 
now. The root of the problem was setting the condor config parameter

GPU_DISCOVERY_EXTRA

to -no-nested, which removed some of the information htcondor needed to 
do the gpu hiding.
