Then the last message repeat on the while using:

pcictl pci0 list (even with pciverbose loaded)
Reports very generic information:
000:01:0: ATI Technologies RS480 PCI Express Bridge (PCI bridge)
001:05:0: ATI Technologies product 5955 (VGA display)


I suppose it is an R300 card (compatible with the Xpress200 480 chipset of ID 5955)
