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


the other factor in HyperThreading which some forgot is whether you
BIOS has support, and whether it is enabled.

works for me on a 2.8GHz Northwood on Intel 865G.
