On SMP systems you can get very high frequencies - on a 400MHz dual-Celeron I
use here I can get a 200kHz signal out to the parallel-port, on a 200MHz PPro-SMP it can reach almost the same frequency. With the reserved CPU you should be 
able to do 200kHz on SMP and posibly more (did not check this on anything newer
than a SMP-celeron).
