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:
