I can't try a real board. But in case this helps, the comments in
sys/dev/ic/i8259.h confirm that the even address is the right place
for sending OCW3 commands.
So does i8259_init() routine in sys/x86/isa/atpic.c, which also
confirms that IMR is the odd address. However, this code is used on
x86 only.
