Actually after looking at the size and slots of PCI-Express x16 vs 
standard PCIe, _no_, you can't. In 
<http://zone.ni.com/devzone/cda/tut/p/id/3767> there's a picture 
comparing PCIe x16 to PCI, PCIe x8, and PCI-X, and there's no way that 
it will fit... Besides the PCI-x has 1 lane while PCI-x16 has 16. That's 
what I get for not having a up to date machine that I could judge this 
from (still stuck in the PCI "dark ages").
