We haven't gotten any reports on this card.
My expectation is that it should just work, but it might require a new
driver PCI table entry.
My expectation was that this card would be two regular chips behind a bus
bridge.

The photograph shows a 64 bit card with a single chip, but the documentation
states the bus type as "32-bit PCI Hot-swap" so the photograph might not
match the product.

(Gripe: PCI cards are not "hot swap".  That is just advertising puffery.
Hot-swap is a feature of the motherboard and device driver.  The usual
implementation is that the PCI card hold-down connects to a switch on the
motherboard which turns off power to the slot.  The driver just treats this
as it would a CardBus device, with eject and insert events.  It's actually
easier, since you get many seconds of warning before the device goes away.
Sometimes CardBus devices are gone before you get the eject event.)
