Strange behavior of PCMCIA-Card DFE-650TXD with Debian Etch

[Niels Stargardt <niels.stargardt@gmx.de>]

Hi,
I use an old thosiba notebook with Debian Etch and an PCMCIA-Card D-Link
DE-660+. Everything works fine. 
Yesterday I found an PCMCIA-Card from D-Link the DFE-650TXD, which is faster
and more comfortable. I tested them under Windows and Debian Etch on an IBM
Thinkpad. The card works fine, so I changed the card in the toshiba
notebook. Surprisingly the card doesn't work. So I checked the
syslog-entries:
On both machine they equal:

Nov  9 19:34:36 onnie kernel: pccard: PCMCIA card inserted into slot 0
Nov  9 19:34:36 onnie kernel: pcmcia: registering new device pcmcia0.0
Nov  9 19:34:36 onnie kernel: eth0: NE2000 (DL10022 rev 30): io 0x300, irq
3, hw_addr 00:40:05:8E:FA:5D

So card would be found. Next I checked lspcmcia, again on both machines the
same result
Socket 0 Bridge:        [yenta_cardbus]         (bus ID: 0000:00:0b.0)
        Configuration:  state: on       ready: yes
                        Voltage: 5.0V Vcc: 5.0V Vpp: 0.0V
Socket 0 Device 0:      [pcnet_cs]              (bus ID: 0.0)
        Configuration:  state: on
        Product Name:   D-Link DFE-650TXD Fast Ethernet Rev. A1
        Identification: manf_id: 0x0149 card_id: 0x0230
                        function: 6 (network)
                        prod_id(1): "D-Link" (0x1a424a1c)
                        prod_id(2): "DFE-650TXD" (0xd661b6dc)
                        prod_id(3): "Fast Ethernet" (0xb4be14e3)
                        prod_id(4): "Rev. A1" (0x5afd938b)
Socket 1 Bridge:        [yenta_cardbus]         (bus ID: 0000:00:0b.1)
        Configuration:  state: on       ready: yes

So it looks for me that the card is recognized on both cards. I don't
remember that I did any special thing at the installation at any of the
notebooks. So the software should be more or less equal. I checked the
kernel-version, on both they are same:
Linux onnie 2.6.18-5-686 #1 SMP Wed Oct 3 00:12:50 UTC 2007 i686 GNU/Linux

The fact that the other card works out-of-the-box shows me that pcmcia is
well installed on both machine, but on the toshiba notebook with the new
card I only see the loopback-device if I call ifconfig :-(

Any hints are welcomed.
