More replying to myself I'm afraid.  I've got stuck trying to do step 2.

The instructions for interrupting redboot say to use:

arping -f 192.168.1.100 && telnet 192.168.1.100 9000

Unfortunately the current version of arping (2.06) doesn't understand a 
"-f" option and I can't find one which does - I presume it would tell 
arping to exit after receiving one reply.  It doesn't seem to be 
possible to emulate it either.

Is there another way of getting into the telnet session?  I've tried 
doing it manually but the window of opportunity seems to be exceedingly 
short.
