In case anyone is interested in the differences between the two, there's a neat article on Tom's Hardware: http://www.tomshardware.com/2005/11/23/pci_express_battles_pci/. I am used to working with PCI-X in servers (as you point out), and the new(er) PCIe interface is what we are talking about with regard to the Intel 3945. In fact, even in the T43, one of the card slots is CardBus (32-bit) and the other is PCIe (ExpressCard; see http://www.expresscard.org/web/site/standardsummary.jsp).
