...my suggestion is 1. Add quirk to detect 430FX chipset, if detected, disable MSI in this platform. or 2. Append boot argument pci=nomsi in OS command line when the OS running on your old platform.

PCI devices save the msi and msix capability offset in pci_dev->msi_cap and pci_dev->msix_cap. When we access PCI device MSI and MSIX registers, we can use msi_cap and msix_cap in pci_dev directly. Remove the pos member in msi_attrib.

...component of the addin card. Wouldn't the lack of support for MSI by the chipset "00:00.0 Host bridge: Intel Corporation 430FX - 82437FX TSC [Triton I] (rev 01)" preclude the use of MSI with buses attached via a bridge?

...bridge? We have no ways to check host bridge whether support MSI routing to CPU, BIOS is responsible for setting and config this in their private registers located in IOH.
