Well, I don't know sharing interrupt between ISA & PCI will be a good idea.
You will get lots of trouble, from hardware perspective (triggering method,
chipset recognition, interrupt acknowledge), from driver code of two
different Ethernet cards! Try to relocate either interrupt, so that they
are different. I don't have a LinkSys personally, but I've configured
lots of machine in my working place with tulip Ethernet card (DEC chip)
and 3c509 coexist, and run happily for months.
My 2 cents,
