Wiggler interfaces operate at a maximum of 500kHz TCK rate - if your target is 
running at full speed, there shoulnd't be a problem because of the missing 
RTCK. I remember reading something about 1/6th main clock rate being safe, 
and I've been able to sucessfully debug a LPC2294 (ARM7TDMI-S) at 3 MHz TCK 
rate.
