Debian AMD64 and Intel CPUs

[T o n g <mlist4suntong@yahoo.com>]

Hi,

I've recently realized that Debian AMD64 is not only suitable for my 
AMD64 but some Intel CPUs as well. 

http://www.debian.org/ports/amd64/ says all Intel CPUs with EM64T 
extension are supported. 

Can someone tell me what kind of Intel CPUs have that EM64T? Any easy 
rule of thumb? E.g., can I safely assume all those Intel 64 Duecore are 
able to run Debian AMD64? 

thanks
