By and large, the required drivers are not modules.  It's possible that 
we might have screwed up in some cases, but I think we've done the right 
thing for the most part.

The built-in wireless device is on USB.

Our activation security system is in an initrd so that the firmware can 
check its signature before booting it.  The whole security thing adds a 
bunch of interesting wrinkles.

As mentioned, our wireless module is on an internal USB port.  To what 
extent does that complicate the situation?
