What were the differences between Chrome and Gecko here, if you recall? 
  I'm somewhat interested.

In any case, I believe the spec is wrong in one aspect: in the case that 
there is a default button, what needs to happen is a click event on that 
button, not just a triggering of its activation behavior.  In 
particular, onclick handlers need to fire and the activation behavior 
should only happen if preventDefault is not called on the event.  For 
example, this testcase:

   <!DOCTYPE html>
   <form action="http://w3.org">
     <input type="text" value="Focus me and hit enter">
     <input type="submit" onclick="alert('haha'); return false;">
   </form>

should alert and not submit.  Yes, I know this is totally screwy.  :(
