Simple ultrasonic transducers behave pretty much like "normal" audio mics so you should be able to plug one into a mic pre-amp, assuming the amp has a good enough high freq response. You could try replacing the mic on the regular micasb board and see if you get anything. However you will have to sample _very_ fast, which the motes may not be able to sustain for very long.
Search for ultrasonic alarms and such online and you'll probably find schematics and kits for the analog part.
