Multiple NIC cards in the same machine and 2.5/2.6

Multiple NIC cards in the same machine and 2.5/2.6

[NoTellin]

I use an iptables based firewall. I currently have 4 NIC cards in 
the machine.

My modules.conf file contains the following lines:

alias eth0 ne
alias eth1 ne
options eth0 -o ne-0 io=0x300 irq=3
options eth1 -o ne-1 io=0x200 irq=5
alias eth2 winbond-840
alias eth3 3c509

This works perfectly fine for the 2.4.x series of kernels up to 
and including 2.4.24

However, I can't get this to work in any 2.5/2.6 kernel. The 2.6 
series of kernels will recognize that there are 3 nic cards but 
doesn't seem to accept 2 copies of the ne nic drivers in memory. 
I've tested this up to and including 2.6.3.

I've tried researching this on the 'Net but I've only been able to 
find references suitable for the 2.4 and lesser series of 
kernels. Could someone point me to the equivalent information for 
2.5/2.6 and higher?

Configuration:

90 MHz Pentium Classic, 64 meg ram, 3 gig hardrive.

eth0 - ISA NE2000 - ADSL connection to Internet
eth1 - ISA NE2000 - Lan Segment 2 connection
eth2 - PCI Windbond - Lan segment 1 connection
eth3 - ISA 3com - Cable Modem (backup) connection to the Internet.

Thank you everyone.

There is no need to load two copies of the ne module.  Just use:

alias eth0 ne
alias eth1 ne
options ne io=0x300,0x200 irq=3,5

Ah-HAH. This must be one of those fundamental differences between 
2.4 and 2.6. At the risk of sounding utterly incompetent, could 
you enlighten me as to what I should have been looking for in 
terms of seach terms. I like to think I'm a decent googler and I 
generally RTFM, but I was totally unable to help myself this 
time.

I was aware that the driver layer is completely different between 
the 2.4 and 2.6 series, but I have difficulty in finding out what 
that means from a practical standpoint. Hence the questions.

Thank you very much for your answer BTW. I play with it later this 
weekend.

No - this is an old feature (it was present in 2.2 and maybe even
earlier).  It is noted in Documentation/networking/net-modules.txt.
