I appreciate the time you've spent on this.  I did try 6.4 again (6.4.1 
actually) and wlan0 did eventually come active.  When I tried this 
before, I probably got freaked by the number of WARNINGs when it wasn't 
connecting, but perhaps it was failing for some other reason.  I didn't 
realize they were only warnings.
