The timer_ack variation exploits the polling mode of the i8259A with the
AEOI enabled. It's a valid configuration. It's needed for a correct
operation of the timer interrupt handler and the NMI watchdog in certain
configurations. What's there in the datasheets you that makes you think
the code is a mistake? A reference would be appreciated.
