I thought your message yesterday indicated you'd found the answer.

You don't setup any kind of routing between CPU cores and devices.
At boot, initially CPU 0 will "own" all interrupts.

You then run a (fixed) version of irqbalanced (preferably the older
version which is not so x86-centric, eg, 0.56) which then distributes
the interrupts between the cores according to what the interrupt is
used for and the load it is imposing on the system.
