    I've seen the marketting literature on the D-Link website for this card
    for many months, but I'm having a hard time finding a seller in the
    USA (i.e. a significant mail-order distributor). 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.
