What if it was Packers/Patriots in Super Bowl 42?

Lets say Favre didnt throw that last pick in overtime and drove the Pack to an overtime win againts the Giants? Then set up a Super Bowl match with the undefeated Patiots. Who do you think you have won? Everyone says that no matter who the Pats played, they would have lost no matter what, because the "football gods" would not allow a cheating team to break the 19-0 record. So do you think Favre could have beat the Pats again?
