I definitley agree it would have problably had a different outcome. Does anyone know that for sure though? No. The officials absolutley sucked up that game, but where was Childress to challenge that Green Bay touchdown? Granted, the ref should have never gotten it wrong, but that's why we have instant replay.
My point is, you can't blame the whole loss on the officiating. Who knows how momentum, game planning, etc. would have changed for both teams with even one changed call, so I don't think you can say with 110% certainty that if calls went a different way the Vikings would have won, which is why the NFL does not over turn who won or lost when they admit a bad call.
The Vikings had chances to win and didn't come through. Was the officiating bad? Yup, absolutley. But at the end of the day, you aren't going to win many games with a coach who has an IQ of 5 and a QB who can't walk throwing 3 interceptions in 7 pass attempts (But if a call is made differently, maybe Favre doesn't force one of those throws or maybe the play never happens where he gets hurt, you can't possibly predict what would have happened if the refs made the right calls)
