two 3c509s with 2.4.x kernel causes irq conflict

I've been using two 3c509s for my router for well over a year now. When I attempt to use a 2.4.x kernel on that box, my NICs both set to irq 10, and I am not able to get them to use any other irq. Does anybody else understand this? Is there a solution? (other than using a 2.2.x kernel - which works) TIA, Steven -- Open Source Software depends on your support.
