If we can agree on this approach, then I'll be using it to pass info
on to the guest BIOS in a follow on patch.

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 :-(
