Ok, thanks. At least it found the PCI card and the BARs. I guess now I need to look more closely at what it wants to do with the BARs. I may need to get a SiI 3112 or 3114 card or make the code think a different PCI card that I have is a Sil card.
Looks like there was a problem in the DirectHW library. pciutils works because it contains its own version of the DirectHW library. I updated the 3 projects so now flashrom should be able to find the PCI card in Mac OS X 10.4.
First verify that flashrom can find the card:
sudo flashrom -VVV -p...
I made forks of pciutils, flashrom, and directhw that you can compile on Mac OS X 10.4 and 10.5 and later.

pciutils works (with directhw) so you can do sudo lspci -vvvnnxxx >...
