Adding a PCI device that doesn't exist (yet)

Hi All,
The PCI interface to our "special sauce" is an FPGA that we're
programming after the OS boots. The hardware doesn't have PCI hot-plug
support, which means we're forced to reboot after programming in order
to re-enumerate the bus in BIOS. Or are we?
I was thinking of replacing the default scan_bus method with one that
calls the default method for most devices and inserts the non-existent
device information into the table at the appropriate time.
Has anyone been successful at this sort of thing?
Cheers,
