For testing my Stratix IV GX development kit from my laptop, I use the following setup:
1. HP Elitebook laptop with ExpressCard slot.
2. OneStopSystems ExpressCard-to-PCIe x1 cable
(the ExpressCard only has a x1 lane in it)
OSS-PCIe-HIB2-EC-x1

http://www.onestopsystems.com/pciex1tox4cable.php 4. OneStopSystems 3 slot PCIe motherboard
OSS-PCIe-uATX-BP-2018
http://www.onestopsystems.com/pcie_atx_bp.php The motherboard uses a PLX PEX8533 PCIe bridge. The datasheet is available under NDA from PLX.
Cheers,
Dave
