Kernel : 2 instances of the same driver?

Hi all!

I have a old Pentium1 computer with 2 network-cards (DEC
EtherWorks 3, DE205) on
ISA bus.
I would like to use this computer as a gateway.
I have a old Linux (2.4) distribution which is currently
running on it, but I
would like to upgrade and try NetBSD 3.0.

The configuration on Linux :

# insmod -o ewrk3a ewrk3 io=0x300 irq=5
eth0: DE205-AB at 0x300, h/w address 08:00:2b:3e:21:09,
      has a 2k RAM window at 0xd0000 and requires IRQ5

# insmod -o ewrk3b ewrk3 io=0x340 irq=10
eth1: DE205-AB at 0x340, h/w address 08:00:2b:92:ad:fb,
      has a 2k RAM window at 0xd0800 and requires IRQ10

The routing between the two networks (between eth0 and eth1)
works perfectly.

I install NetBSD 3.0 : none of the cards is recognized.
I decide to create a custom kernel from the GENERIC kernel.
I make a copy of /usr/src/sys/arch/i386/conf/GENERIC.

The cards are sharing the same lc driver :
   lc0	at isa? port 0x320 iomem ? irq ?	# DEC EtherWORKS III
(LEMAC)
I try to comment this line and replace with
   lc0	at isa? port 0x300 iomem ? irq 5	# DEC EtherWORKS III
(LEMAC)
I recompile and reboot : it works, only for the first card
(what I expected).
Then, I try the following :
   lc0	at isa? port 0x300 iomem ? irq 5	# DEC EtherWORKS III
(LEMAC)
   lc1	at isa? port 0x340 iomem ? irq 10	# DEC EtherWORKS
III (LEMAC)
I recompile and reboot : it does not work: only the first
card is recognized.
Then, I try the following :
   lc*	at isa? port ? iomem ? irq ?	# DEC EtherWORKS III
(LEMAC)
I recompile and reboot : it does not work: none of the cards
is recognized.

What do I need to do in the configuration file in order to
have the two cards
recognized from the kernel?

I thank you in advance for your help,

Sylvain.

Please post dmesg output in each case.
