I noticed that earlier message just as I got your reply.  D'oh!
(That's what I get for reading mail in reverse.  8-)

Well, something about this device is causing the probe to go source.
I'd try using the BIOS configuration menu thang to turn off
synchronous negotiation, and any other negotiation you can.  (Yes, I
know, sync used to work, but hey, it might be broken.  Get to a
working configuration by disabling everything, then enable things one
by one to find out what's breaking things.)
