I don't think so; from what I can tell, the ADD2-R cards use the top 4
lanes for the first ADD2 card and the next four below that for the
second. But, given that ADD2-R cards are generally used for BTX
motherboards, and given that Intel BTX motherboards often come with
on-board SDVO support, I suppose it's possible. I can't remember if I've
already tried this.
