Correct.

We deal with a similar situation by using a PLX9080 to provide the
PCI interface. This handles the configuration space so that we can
do neato things like let the driver reload the FPGA at will. The
FPGA does *not* implement anything PCI, that is up to the PLX chip.

Which by the way is a "bridge" chip (PCI to i960 bus) but not a PCI-to-PCI
bridge.:-)
