    Are you saying you would prefer we create our own irq handler something
    like this rather than using the standard i386 handlers?

    irqreturn_t vmi_timer_interrupt(int irq, void *dev_id)
    {
    local_event->event_handler(local_event);
    return IRQ_HANDLED;
    }

    ?? That's fine with me.
