The doc indicates that the ht flag is kept for backwards compatibility (for
licensing, etc). Now the mystery is solved.

The dual-core Xeon family does have HT available as well, so you can get 2
real cpu cores each with SMT capability. Of course, you need well structured
software to take advantage of that, but that was a given for everything from
HT onward!

Thanks for the help!
