My guess is that if the card is like the other Sierra card, it
attaches as an OHCI on the cardbus and has faked up serial devices
attached on the fake USB bus.

See if the card will attach as a USB controller by uncommenting the
"CardBus USB controllers" section of  GENERIC.

Assuming it attaches, then try adding this to your kernel:

ugensa* at uhub? port ?
ucom*   at ugensa?

If that works, you can talk to the card on ttyU0.

the ugensa stuff is a gross hack and needs to be improved, and will
spew error messages during attach that you can ignore. Also, note that
if you're running current, there was a bad bug until recently that
caused panics when attaching a USB cardbus controller -- you'll want
to update to very very current to avoid that.
