You will need more changes to make interrupt work. Especially if the
particular IRQ that you are using here is not used by any other PCI
device in the system. Then BIOS won't report anything on that IRQ and
all the things done in setup_IO_APIC_irqs() should be done for this
particular IRQ. And it will depend on whether IOAPIC/PIC is ised for
interrupts and such things as well. Atleast that what I remember from
last time I got HPET to work with IRQs other than IRQ0 and IRQ8.
