Good call Bob, and let me see if I can tke a shot at this.
The XL parts have a CFI querry which occurs during the initialization of the flash. Failures at this point in the process signify that the FPGA has been configured sucessfully, and the design running in the FPGA can't talk to the flash. The talking to the flash includes status checks.
Double check the wiring and make sure all the signals are wired up properly. There could be a data pin wired to the wrong pin on the FPGA or something like that. If you have EDK you can try accessing the flash from that too and see if the same thing occurs.
