You *MUST* share the interrupt. NEWCARD only uses PCI interrupt
and you have to share it. The card *WILL* work with shared
interrupts. The card has *NO*CLUE* it is sharing interrupts.
Why must they not have a shared interrupt? I've never seen a card
that doesn't work with shared interrupts.

Right. On 4.x you could use ISA interrupts. That option is not
available with NEWCARD.
