Group Policy scripts with WPA2 WiFi are not launched

We setup a WiFi network with WPA2.  It uses User certificates, so wireless kicks in only after username/password have been entered.  The problem is that with this scenario a laptop thinks it is not on the network when it begins a login process, so AD's drive mapping, as well as Group Policy login scripts are not launched.

Is there a workaround for this?  Can user certificate be authenticated before the login process kicks in?

If your users are in need of these resources, an quick and easy fix would be to create a batch file on the all users desktop that calls for the script from a share on the server.   after they login and establish connectivity, they double click the batch file and scripts will execute as written

Can you not make them machine certificates? or are they shared computers.

OK, a MS TechNet article available for download here: http://technet.microsoft.com/en-us/library/cc527055.aspx answers my question.  Chapter 6, page 151 is where it starts to get interesting.

The key here is to setup a Group Policy that is configured for WPA2 with re-authentication.  Re-authentication uses a computer certificate when nobody is logged in, then switches to computer/user certificates when somebody is trying to login.

It's important to note that only Vista or Windows Server 2008 will let you configure a group policy for WPA2.  I also couldn't configure re-authentication on a single computer, without getting group policy involved.
