I was bitten by this same card just today, as it happens.  Here's what to
do.  What I found was that the card manager chirped happily when I slotted
the card into the bus, but (a) I got a link light but no connection, and (b)
in X, the display went blank immediately if I stopped moving the cursor. 
Neat, I guess.  Not useful, but maybe neat.  Definitely weird.

Doing "lsmod" showed that the "cb_enabler" and "tulip_cb" modules were
loaded.  Tulip?  The PCC-T is supposed to be a 10baseT-only card.  Tulip is
a 100baseT-capable chip.  This had to be wrong.

cardctl gets its information directly from the card, not from the
/etc/pcmcia/config card list.  As a consequence, cardctl ident "lies" about
what it thinks the card is.  To "cardctl ident", it shows up like this:

  Socket 0:
    product info: "corega K.K.", "corega EtherII PCC-T"
    manfid: 0xc00f, 0x0000
    function: 6 (network)

None of the "corega" listings in the config file are bound to the tulip_cb
driver, so the text description of the card in the config file was being
ignored.

Setting "tail -f /var/log/syslog" while inserting the card told a different
story:

Darn.  That's not worth 2,800 yen.  Checking /etc/pcmcia/config turned up
the following entry for the Allied Telesyn card that uses the tulip driver:

  card "Allied Telesyn AT-2800 10/100 Fast Ethernet"
    manfid 0xc00f, 0x0000
    bind "tulip_cb"

The identification was turning on the "manfid" line --- note that the
numbers there for the PCC-T and for the AT-2800 are the same.  It may be
that "manfid" is given priority, on the assumption that numbers are less
ambiguous than text strings.  Oops.  In any case, things worked when I
commented out the AT-2800 entry (completely), and added the following entry
for the PCC-T:

  card "Corega PCC-T Ethernet"
  #  version "corega K.K.", "corega EtherII PCC-T"
    manfid 0xc00f, 0x0000
    bind "pcnet_cs"

I don't think you need to have the card version string commented out
like that -- that is left over from my tour of possibilities.  The key
seemed to be to eliminate the conflicting entry for the AT-2800.

Once you've made these changes to /etc/pcmcia/config, restart card services
with (in Debian):

  /etc/init.d/pcmcia restart

Now when the card manager chirps, you should get a net connection.

Let us know if this doesn't work.  But I'm 99.9% sure that the above steps
will put you in business with that card (this message is being sent through
one of them :-)

Cheers,
