3rd Generation Opterons were the first to include SVM support.  All 3rd Gen 
Opterons have 4-digit model numbers.

3-digit model numbers are 2nd and 1st Gen Opterons.  They do not support 
SVM, which means they cannot run hardware-assisted VMs (HVM) and thus, can't 
run Windows.

Note how there is no mention of "svm" or "vmx" in the flags line.  This 
means there is no support for hardware-assisted VMs.
