I might be wrong but I always thought the Vegas Oddsmakers base the line on analyzing statistics, history, etc. and then gamblers move the line accordingly if they start betting heavily on one side. I don't mean to say they sit there and look at every little thing but I would guess that the Dome thing favors the Packers. If the game was in Kansas City, I would guess it'd be an even spread. But again, I don't know a whole lot about the odd-making.
