Then we will double check.
The Xen hvmloader doesn't break since it only supports one chipset. But SeaBIOS checks for the exact vendor/device ids since Q35 support was added. If you want to add this feature, try to implement it in a way that is a bit more forward-looking. I'm sure that Xen sooner or later will want a PCIe chipset, otherwise things such as AER forwarding are impossible. Paolo
