On 6.X including RELENG_6 you need to use the SMP kernel config in
src/sys/i386/conf and on CURRENT just use GENERIC kernel config.
then add machdep.hyperthreading_allowed =1 to /boot/loader.conf
reboot
the other factor in HyperThreading which some forgot is whether you
BIOS has support, and wh

What? I've never added lines like those...
They always seem to have the correct values for me:
Here it is on 4.8:
# sysctl -a | grep smp
machdep.smp_active: 1
machdep.smp_cpus: 2
and 5.3:
# sysctl -a | grep smp
kern.ti

building a new system, processor is:
