Now that PIIX3 contains the new isa-pic, it is possible to instantiate PIIX3 IDE in the PIIX3 southbridge. PIIX3 IDE wires up its interrupts to the ISA bus in its realize method which requires the interrupt controller to provide fully populated qemu_irqs. This is the case for isa-pic even though the virtualization technology not known yet.
