Gosh, that's interesting, I hadn't noticed that on the wiki. I will find that advice helpful too.
But to answer your question, the following line is relevant:
That tells you that the ROM is at fdf00000 so I think you need to enter:
setpci -s <pci_bus_id> ROM_ADDRESS=fdf00001
(Note that the address should have its lowest bit set in the setpci command. Looking at the include file /usr/include/linux/pci_regs.h suggests that the lowest bit is an enable bit.)

Some users have reported they also need to do:
# setpci -s <pci_bus_id> ROM_ADDRESS=xxxx0001
# setpci -s <pci_bus_id> COMMAND=2
replace <pci_bus_id> with the PCI bus ID and xxxx with the hex
digits you can obtain thru lspci -nv .
Which 'hex digits' do they mean? My ouput for example:
Gosh, that's interesting, I hadn't noticed that on the wiki. I will find that advice helpful too.
But to answer your question, the following line is relevant:
[virtual] Expansion ROM at fdf00000 [disabled] [size=128K]

setpci -s <pci_bus_id> ROM_ADDRESS=fdf00001
