Xircom cardbus NIC (dc0) not working in 2.2.1

[Tim Darby <t+dfbsd@xxxxxxxxxxxx>]

With a Dell Inspiron 8000 laptop and a Xircom cardbus card, I cannot
connect to anything on the network.  DHCP will not assign an address
to the card and it won't connect if I manually configure the address
either.  This card was working in DF 2.0.  As you can see from the
attached dmesg, I get several "livelock messages" when this interface
is config'ed in rc.conf and I get the "dc0: watchdog timeout" message
every 5 seconds.  The xl0 built-in interface on the laptop works fine.
 Note that if I boot the latop without the card and then insert it, I
immediately get the message "intr 10 at 40001/40000 hz, livelocked
limit engaged!"

I'm starting to get the feeling that I'm the only one that uses this
silly card with DFly.  Are you guys trying to tell me I should toss it
and buy a decent card? :-)
