[CentOS] cyclades driver on centos 4.1

I have a 5 year old machine that had a working cyclades8ys (8 port ISA 
rs232) card.
I installed centos 4.1 on the box. I installed the kernel source and 
rebuilt the
the kernel, did menuconfig  and seelcted the cyclades module.
Did the modprode cyclades and got some driver information echoed to
the screen but it did not detect the card.

Does udev have anything to do with this?

Does any one have an old ISA cyclades card working on centos 4.1?
Can you share how?

Thanks,

jerry
