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

No, it's not a bridge.  It's just a card, but I was under the impression
that you needed hardware support for hotplug?

Dave Aubin had been looking at this and he concluded that without
hardware support there needed to be some enumeration present at the time
the Linux kernel loads.  Presumably this would be provided by the BIOS.

This is why I was looking at some way to force an entry into the bus
scan of LinuxBIOS, thus providing the enumeration that the hotplug
kernel would need.

the reason being you don't want to embed the bitstream in linuxbios, 

Are you sure that you can't take advantage of the hotplug stuff in 2.6
your device? Is your device a bridge or ...
