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.
