Centos (i think any version) doesnt show HT enabled , or 2 cpus as RH or other distros do , so i think ur ht is enabled but it will not show up in Centos. Even Dual Xeons with HT show only 2 processors instead of 4.

So i guess new centos doesnt have that feature or maybe ur server is not ht enabled?

2.6 kernel does not show ht correctly sometimes. This is most likely due to teh changes for the exploit that was found in ht
