I believe you to be mistaken in this belief. If you take Ivan's patch,
conf1 is used for all accesses below 256 bytes. lspci -x only dumps
config space up to 64 bytes; lspci -xxxx is needed to show extended pci
config space.

"Bill, look, we understand that you're interested in selling us this
operating system, but compare it to ours. We can't possibly take such
a retrograde step."
