Thanks for the help!
PCIe 0 has an FPGA connected - it is behaving as expected. PCIe 1 has the
PLX PCIe switch followed by a pair of ASICs - they are the ones generating
the error.
Here is /proc/iomem:

And here is dmesg, captured after the failed modprobe, so you can see
those error messages (DEBUG enabled in pci-common.c and pci_32.c):
