Glancing quickly at a recent kernel tree, I still see a driver for this
piece of hardware. I wonder whether the card is not being found because
its in PnP mode and therefore the kernel doesn't see it for whatever reason.

Attached is a file we cary in Ubuntu that can help get this card working
again in PnP mode. No idea if it will help you, but it may be worth a try.
