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.
