Wow my thread really took off.  Disabling the eth0 (and eth1) was a good
idea, but no joy.  There isn't any physical network cables plugged into the
computer, just the wireless device.  To test it, I basically unplug my
router and give it like 5 minutes for Kubuntu to disable wlan0, then I plug
the router back in.  Once it is plugged back in nothing happens, wlan0 does
not automatically reactivate.

I haven't tried wicd yet because it isn't in the repos (at least not the
default ones).
