With pci_conf_debug=1, pci_configure_bus(9) shows:
---
 :
PCI: bus 0, device 10, function 0: id=ffffffff: Vendor=ffff, Product=ffff
PCI: bus 0, device 11, function 0: id=ffffffff: Vendor=ffff, Product=ffff
PCI: bus 0, device 12, function 0: id=ffffffff: Vendor=ffff, Product=ffff
PCI: bus 0, device 13, function 0: id=ffffffff: Vendor=ffff, Product=ffff
PCI: bus 0, device 14, function 0: id=ffffffff: Vendor=ffff, Product=ffff
PCI: bus 0, device 15, function 0: id=ffffffff: Vendor=ffff, Product=ffff
PCI: bus 0, device 16, function 0: id=ffffffff: Vendor=ffff, Product=ffff
PCI: bus 0, device 17, function 0: Data access exception

It seems to fail in pci_conf_read(9), so maybe its maxdevs should be 16.
I change genppc_pci_bus_maxdevs() and now it seems to work more:
