patches, cleaned up and heavily reworked by me. Basic algorithm is the same, although the code structure is now quite different. Main differences: - Initialization path is totally different. - We use the `compat router' information, if present, to determine which PCI ICU driver we should use. - Fixup configuration headers on devices not on bus 0.
