The ne2k-pci driver will share IRQs. The 'ne' driver will work for PCI cards, but is intended for ISA cards. It will not share the IRQ.
Documentation for the ne2k-pci driver is at http://www.scyld.com/network/ne2k-pci.html

Is the ISDN card a PCI device? If not, it cannot share IRQs. If it is a PCI device, the driver is broken.
