init_module: No such device (with on board network card)

I'm runnig the installed version of Knoppix 3.3 on NVIIDIA nForce2 Series motherboard and trying to install the on-board network card.
After the driver has been successfully compiled I'm receiving following message for insmod:
root@box:/home/knoppix/tmp/3c90x-102# insmod 3c90x.o
Warning: loading 3c90x.o will taint the kernel: no license
See http://www.tux.org/lkml/#export-tainted for information about tainted modules
3c90x.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg

thanks for any help

After I gave up my desperate way of driver stallation I found some very useful information:
http://lists.debian.org/debian-user/.../msg03577.html

I followed the instruction and it's working fine now. Thanks to Vincent. It's really great that he reported each single step how he brought his network card working on debian. So, I put the link here for next nvidia nforce user :-)

I got my driver from:
