Net booting in an 802.1X environment.

Our organization is planning to switch to 802.1X authentication and our current method for deploying Mac images is through Deploy Studio. We have began testing different pieces of software and realized that we can no longer net boot. I have tried booting while hold the N key and it attempts(with the spinning globe) but goes straight into OS X. I tried holding the Option key but it only shows the harddrive, recovery, or wireless. I was hoping it would give me an option to authenticate.

Is there a way around this problem? We have several computer labs that will need to be able to connect to our Deploy Studio server...
