Clarification about AMD64 port for Core Duo

[Frank Lay]

Hello,

The CURRENT (9.0R) release notes have the following to say about the 
AMD64 port:

-------------------------->8-------------------------------------
As of this writing, the following processors are supported:
...
* All Intel Core 2 (not Core Duo) and later processors
...
-------------------------->8-------------------------------------

Yet I see many people on the Internet claiming that they're running 
FreeBSD version <= 9.0 successfully with Core Duos. What's the meaning 
of this? I own a C2D E8400 (Wolfdale) processor, would I perhaps be 
safer chosing the i386 port? Or is this all hyperbole?

I'd appreciate any time you could spare explaining this to me.

Cordially,
    Frank.
