I had not properly removed all of the 'eth0' definitions from '/etc/network/interfaces'. After cleaning things up so that only the loopback definition and 'allow-hotplug wlan0' remained, the suspend and resume worked as designed.
The problem was that with the network-manager was not actually managing the wireless connection, so eth0 was defined as the default connection.
