It requires that you are using a serial console, and that you have

  options	ALT_BREAK_TO_DEBUGGER

in your kernel config.  It looks like that's not in the stock RPI-B
config.  There's a different break sequence for using a keyboard and
video console (and I don't even know what that is, it's not something I
ever use).
