PCMCIA network card problem

Hello everyone,

I'm trying to enable a PCMCIA network
card (in particular, D-Link DFE-680TX)
in tomsrtbt version 2.0.103. Linux
supports this device (at least under the
2.4.18 SuSE 8.1 kernel).

When the diskette boots, I get messages
about my PCMCIA is not recognized,
but it seems like the general PCMCIA support
is working, because a lsmod shows the
following:

ds                   5904      2
i82365            21058    2
pcmcia-core    43544    0    [ds i82365]

In see in
http://pcmcia-cs.sourceforge.net/ftp/SUPPORTED.CARDS

[pcmcia-cs driver: tulip_cb] [x86,ppc]
...
D-Link DFE-660TX, DFE-680TX
...

... so I've tried insmoding tulip_cb.o (in add-ons/kernel/pcmcia/ of
the tomsrtbt repository), with the following errrors:

insmod: unresolved symbol unregister_driver
insmod: unresolved symbol register_drive

May I need additional modules? (maybe tulip.o, the
one that the SuSE kernel seems to use, but I cann't
find it in the add-ons repository).

Any help about solving this problem is welcome.
Thanks in advance!
