Can you try lcpci with direct hardware access? By default lspci only lists those devices that Linux found and enumerated. Direct hardware access does the CF8/CFC dance. If we find it that way, then its a hunt to figure out why Linux silently discarded it. Also, check the I/O ports you are trying to access in /proc/ioports to see if anybody has claimed them.
