The hot rodders trick for beating this is to not apply spark until the
starter has the motor up to speed, ie seperate switches for the ignition and
starter.  I've set up my boat(460 ford) and high performance cars this way.
 It dosn't seem like it would be that difficult to implement in software.

Ed Lansinger discussed another scheme in Circuit Cellar Ink #63.  He fired
the plug at exactly TDC at cranking speeds.  The advantage of this scheme
(besides being much more elegant than 2 switches) is that race vehicles can
be bump started.
