I used to use ifplugd, but NetworkManager is supposed to do more, 
particularily as it relates to WPA and crap like that.

But, I think you are pointing a finger at NetworkManager not cleaning
out the IPv6 info properly, or possibly that I am not telling
NetworkManager about the suspend properly.

I essentially run only enough of GNOME-Panel to let network-manager
work,  so it's possible I'm missing some element.
