Well, I remember reading the J. Michael Straczynski-written Amazing Spider-Man
issues that led into Civil War
, and in them it seemed that Stark held pretty much the opposite view on registration than he did in CW. Although I think the idea was that he was anti-registration until the tragic incident that set off the miniseries changed his mind. But I do recall reading reviews complaining that a lot of characters were written inconsistently among the various series involved in the crossover.
