The obvious alternative would be a blacklist. With all the unknown broken-MSI devices out there, this is going to be a nightmare. But would you accept patches that make the drivers test, when attaching, whether the MSI interrupt actually works, and fall back to INTx otherwise? This would break only for devices that blow up completely when configured for MSI; I don't know if or how many of those exist.
