Check LINT (/usr/src/sys/i386/conf/LINT):

#####################################################################
# SMP OPTIONS:
#
# SMP enables building of a Symmetric MultiProcessor Kernel.
# APIC_IO enables the use of the IO APIC for Symmetric I/O.

#####################################################################
# 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

Did you disable the cpu I386/I486 lines in your custom kernel?
