It looks like NHTSA is requiring a tire pressure monitoring system by Sept 2005, which would put it into the 1st Gen Fed Elise:

Is there one already? I know some cars are using the ABS wheel rotation sensors to measure low pressure by diameter, while some use in-wheel transmitters. Does the Elise have one of these already?
