    Sounds good to me. In Xen we have 1024 event channels which we need to
    map down into a smaller irq. Aside from the complexity of maintaining a
    mapping table, that's not a huge issue for now, but when we start
    exposing pci devices to guests it all becomes more complex. The ideal
    for us is to simply use event channel == irq, which this would allow.
