I would imagine the the card would 'just work' as long as it has a programming interface that is compatible with one of our drivers. We don't have MSI support yet so interrupt latency might still be a small issue (though it's debatable whether MSI gives better or worse latency than legacy PCI when you're dealing with a heavily loaded root complex), but interrupts should still work fine in legacy mode. I have several machines that can take a card like this and I wouldn't mind having one just for validation purposes, but it's probably not a big deal. Scott
