Still nothing at this point.

Well, this produces at least an error in /var/log/messages:

Aug 28 08:01:02 localhost nm-dispatcher.action: Script
'/etc/NetworkManager/dispatcher.d/static' exited with error status 2.

So that's something, anyway. I don't see any errors in the script, but
I confess that I'm a second-rate bash scripter.
