well interrupts can be shared so lets first make sure the modules.conf
has the correct interrupt.

I think he just needs to make sure the driver is trying to use the
proper irq that the card is set to. he should do this

lspci -v

or

cat /proc/pci

that should list several devices, and you should from that be able to
tell the irq your network card is on.

if you do not have 2 network cards installed, you should only have 1
entry for a network card in /etc/modules.conf

alias usb-controller usb-uhci
alias eth0 3c509
options 3c509 irq=5
alias eth1 3c509

I would eliminate altogether or just put a # in front of that options
line, and see if that fixes it. but first if you do not have 2 cards,
erase that alias eth1 3c509 line altogether.

i really expect the 3c509 should work without manually telling the
driver which irq the card is set to, what does the readme say about that?

as a note I have an nforce chipset and my modules.conf has this for
network settings

alias eth0 nvnet
