Okay - interesting. 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.
