You seem to have missed the remaining, Mandatory, lines in LINT...
# SMP OPTIONS:
#
# SMP enables building of a Symmetric MultiProcessor Kernel.
# APIC_IO enables the use of the IO APIC for Symmetric I/O.
#
# Notes:
#
# An SMP kernel will ONLY run on an Intel MP spec. qualified motherboard.
#
# Be sure to disable 'cpu I386_CPU' && 'cpu I486_CPU' for SMP kernels.
#
# Check the 'Rogue SMP hardware' section to see if additional options
# are required by your hardware.
#
# Mandatory:
options SMP # Symmetric MultiProcessor Kernel
options APIC_IO # Symmetric (APIC) I/O
There are other such as ACPI if you want to try.
