You can use either 'pci-config' (distributed with my diagnostic
programs) or the standard 'lspci' program.
I wrote pci-config to track down exactly this sort of problem.  It
reports the PCI configuration space settings, including power state.

As I understand it, those settings control only the PME signal that
allows the machine to be woken up.  There is no software control over
providing stand-by power through the WOL cable.  So a misconfigured
CPU-PCI bridge prevent wake-up, but you should still see link beat LEDs.
