That's exactly what I intended to do all along, since I knew that was the 
most commonly used of the three drivers. I only noticed after I already 
had the panic log and had already put the LapLink cable away that I had 
used the rtl8187b dongle for the test instead of the zd1211b one. I'll 
try to remember to redo the test the next time I need to reboot this 
laptop for anything.
