I've scanned the PCI information under Documentation/PCI in the source tree, but could not find this information. I am not sure if PCIe gen 2 requires special software support in the PCI layer, or if the hardware hides any PCIe version differences from the Linux PCI driver.
Thanks,
Andrei
PS. Please cc me on the response...

PCIe 2.x works fine with Linux. We don't support all of the PCIe 2.x
extensions though, so depending on your device not all features may be
enabled.
