Mine says 16X with both the 6800 and the 7800GT and 8X in SLI maybe it is some sort of driver issue.
Thats wierd it might be some sort of glitch I havent seen on this board before, so far I have had good luck with them and all mine run 16X.
There must be a problem with that board I checked 2 other systems I have built with it and they are all running nat 16X with one card.
Thats wierd about the 8X PCI-E mine runs full 16X with 6800 or 7800GT and 8X by 8X in SLI maybe there is a BIOS update you need?
