Core 2 Duos have the EM64T extensions. Core Duos (Yonah) are a mobile
chip only, not a full line of processors like the Core 2 architecture
(Merom, Conroe, Woodcrest).
I suspect the Core 2 chips do not suffer from the same security
implications as HT-enabled processors. I'm not certain, but I thi

I believe so, but the blurb that I read that in is from 2003. There's a
good chance someone will jump in to correct me. :)
It was in /usr/src/UPDATING:

So, 50% is used for processes and the other 50% to handle hardware

I've read that SMP should be disabled for performance issues (I did not know
that before installing freebsd). I have a P4 3GHz with hyperthreading
technology. I have the SMP-GENERIC kernel and it only launches one cpu. So,
I've decided to disable SMP from BIOS. Is that ok?, knowing that I have a
