    I have a 1500R, not a 1600, and I'm not familiar with the 5.x branch, but
    if it's the same as 4.9, the conf file format is:

    options SMP # Symmetric MultiProcessor Kernel
    options APIC_IO # Symmetric (APIC) I/O

    ... where you have "device apic", instead of "options APIC_IO".
    And my dmesg contains the following lines, where your dmesg doesn't seem to
    show any sign of APIC configuration or multiprocessor info:

    Timecounter "i8254" frequency 1193182 Hz
