Which I should mention, AUTO_EOI_1 is thought to work on all systems, but
AUTO_EOI_2 is thought to not work on a good number of systems. I seem to
have crossed wires somewhere thought, I thought AUTO_EOI_1 was turned on
by default quite some time ago, but it doesn't seem that way in the code.
Perhaps it was done on the 2.1 branch only or something. DG, are you
listening? :-) Do you remember anything about this?
