Digital DS21143 is killing me!

Hi, I'm desperately trying to get a DEC DS21143 to work with Red
Hat 5.2. Apparently, this card is has all sorts of crazy
interfaces on it, but I just need it to work with thinnet
(10base2). My latest theory is that somehow the "autosense"
feature is getting snarled up. The card works flawlessly under
Windows NT--It finds the media type (NT also thinks the card is a
22142). But with Linux, I can't get packets in or out of the
machine...
So, I tried to force it to select 10base2 with the "options=1"
option in /etc/conf.modules, and I also tried compiling the
module with that option hard-coded. But it wont take. It can't
change over to 10base2 for some reason.
I get these messages:
Feb 9 04:46:45 fifi kernel: eth0: 21143 negotiation status 000000c0, 10base2.
Feb 9 04:46:45 fifi kernel: eth0: 21143 negotiation failed, status 000000c0.
Here's a complete list of messages that occur when the card boots up:

Feb 9 04:46:45 fifi kernel: eth0: Testing new 21143 media 10baseT.
Then, I also get these messages, over and over again:

Feb 9 04:51:45 fifi kernel: eth0: 21143 100baseTx link beat good.
It's driving me crazy!!
How can 100baseTx link beat be good? All I have connected is a big fat
10base2 coaxial cable to the BNC connector.
I've looked through all of the mailing list archives, but I can't find any
more information on how I should go about fixing this problem--assuming
that it can be fixed. Does anyone have any helpful suggestions? Does
anyone know what I can do? I really don't want to have to buy a whole
new ethernet card.
Thanks in advance for your help!

PS: Here's some nice diagnostic information that might be useful in figuring
out what the problem is...
