    I think you're wrong.

    The RTC is _still_ connected to the timer pin on the CPU,
    which means it gets a very high priority interrupt, which
    is exactly what we want.

    IRQ0, where the PIT lives, is the lowest priority interrupt.

    In 2.3.47, all vestages of PIT-as-timer will be gone.
