The major difference was that Windows and the Video Card Drivers doesn't mind if you do something like attaching a 2014 PCI Express Video Card directly to the 1996 440FX PCI Host Bridge, a configuration that is physically impossible, but that in virtualized enviroments works in a miracleously way simply because PCI and PCIe are compatible at the protocol level.
I can confirm that, i remember a slide from AW's presentation where it is said that windows doesn't care about topology, but linux does. It was one of the reasons why the Q35 machine could be desired. Also, it is retarded, but possible to attach ioh3402s to 440FX. On the other side, with Q35 you get better USB and AHCI(sata) controllers. Which you don't care about because of virtio-scsi existence.
