Actually, a 2.4 could have HT.

"Intel extends Hyper-Threading Technology? to a variety of desktop PCs, with
the new IntelŪ PentiumŪ 4 processor, featuring an advanced 800 MHz system
bus and speeds ranging from 2.40C to 3.20 GHz. Hyper-Threading Technology
from Intel enables the processor to execute two threads (parts of a software
program) in parallel - so your software can run more efficiently and you can
multitask more effectively."

P4's below ~3.1GHz do not actually provide logical CPU support.
