Okay.  I've dropped the manufacturer an email asking whether this
device is supposed to work in a mechanically x16 slot which has only
one lane available to it.

The primary chip on the board is indeed marked with the JMicron logo
and "JMB585" (it's also marked "2143 QHBA1 A" and "E771C0011"), but
there are numerous other components, including at least two other
chips, there....

I may have to do some such.  I'll see what Vantec has to say.  (In
particular, I don't want to do anything permanent to this card while
there's still some chance I may need to RMA it.)
