imo, we shouldn't be draining fifos before a reset in hardware that doesn't 
matter -- it's just a waste of time.  if it were a CONFIG knob for people, i 
wouldn't complain too much, but i still wouldn't see the point ... you'd lose 
like maybe 2 or 3 chars at the end of a msg ?  not that big of a deal.
