    I see Steve Fosset is trying for another solo baloon circumnavigation but it
    doesn't appear that he will cross the equator. What is the definition here?
    Clearly just a short stroll around the pole wouldn't answer.

    Ballooning counts a "circumnavigation" a little bit differently.

    the official rules are (bottom 2/3rds of the page):

    Fossett's web site summarizing this as:
    Q: What constitutes "around the world"; The Earth is 25,000 miles around at the Equator, but Fossett is staying well south and probably won't travel that far. Will his flight still qualify?
    Yes. As established by the Fédération Aéronautique Internationale - the International governing body of aeronautics - the rules say a pilot must set a course of waypoints within a band of the Earth that stays at least 30 degrees latitude south of the North Pole or 30 degrees north of the South Pole. The lines joining those waypoints (on a "great circle" projection) must stay outside those polar caps, although parts of the actual flight can drift inside them.
