Use DIMM with two DQS pairs swapped?

I have a prototype board that uses a DDR2 SO-DIMM. Due to a design error, the DQS6 and DQS7 pairs are swapped. Would the design still work? The DDR interface is very slow on this board and all...

Thanks for all your suggestions. I'll get the board back from assembly next week. If it doesn't work as-is then I'll try swapping the DQ-groups. If that doesn't work then I'll patch the board.
