Thanks Steve, I've emailed you.
Paul, I got
this one.
It works fine, although the power cable for it (which plugs into USB2 or PS2 port) doesn't appear to work, at least not for the firewire camera. The cable is also not long enough for me, as the PCMCIA card is on the opposite side of the laptop from the USB2 port, so it doesn't reach without getting in the way.
The card itself seems to work fine. I just use a Belkin firewire hub to power the DMK.
