I'm having a bit of trouble confirming some information.

From what I can find , do only cards from the HD 3000 series and higher support more than 2 cards in crossfire? I actually cannot find any instance of someone running anything in the 2000 series or x series with more than two cards.

I suppose it would make sense seeing as the 3850 x2 and 3870 x2 were the first high end dual gpu cards from ati that would have required crossfire x in order to add another card.
