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.
