Given the new isa qdev support, maybe it would be better to hook into

Hi Anthony,

In principle that would be good, the problem is just that the most of
the code still brute force messages with the i8259 array directly,
including the new ISA code. It really needs to be fixed to reference
the ISA IRQ number and not the i8259 array directly :-(

How about making isa-bus.c own the i8259 array then? We could pass it to isa_bus_new. Then switch over to reference isa irqs by number. That allows isa-bus to keep track of the allocations. Maybe it makes sense to kill the sysbus-style isa_{init,connect}_irq split and have a irq bus property then.
