Where/how are you initially configuring it? If you put it into /etc/network/interfaces I would expect it to "stick".
All the same, you're going to lose "vital" seconds having the network cable disconnected and reconnected while the network goes down and back up. Any reason not connect a hub/switch between you and the switch you're configuring so that your laptop's network connection stays up? You can get small 3-port USB-powered switches which are great for stuff like this if you're not in an office.
Maybe there's a way to stop the network connection going down on cable disconnect in the first place?
