Is this the box on your blog at http://blog.agdunn.net/?p=391 ? If so those cards are to be used in the Supermicro UIO slot, which is basically just an inverted PCI Express slot. However since there is only one UIO slot per board they might have not tested compatibility with multiple in the same system. I do have one of these boards installed on an Intel board without issue. I have had the 7 drives connected in mdadm RAID for almost 2 years now with no dropouts. You might try a port multiplier since the card supports it and one drive isn't going to use the full bandwidth of a single SAS cable.
