So I am guessing that these are PCI cards, and the system BIOS is allocating
the interrupts? Can you please confirm.

In many BIOSes, you can allocate specific IRQs to PCI slots. But that should
not be necessary. If it's an ISA card then you allocate IRQs on the card
itself (in the case of 3com cards using the DOS utility supplied)

Yes, it could in principle be any of the problems I listed before. Have you
tried replacing your xl0 card with another identical one? Which exact model
of card are you using? Can you show the dmesg output which detects it? I
seem to remember that some older 3com cards had problems, but it depends on
the exact model number.
