hyperthreading has been supported since 2.4.19 or 20 as far as I recall.
Explicit knowledge of the layout and association of dual core chips on
the other hand I believe is new in 2.6.12. Earlier kernels may still
recognize it as two cpu (each with hyperthreading) but may not do the
optimal thing for scheduling on a dual core machine.
You would certainly need the -smp version of the kernel if you want to
take advantage of either of dual core and hyperthreading.
