Can you point out which processors have this hardware -- are they the
64-bit models only?  My instincts tell me that the 64-bit hardware
could virtualize a 32-bit machine -- but that's a pure guess on my part.
Since people recently asked on NetBSD's port-xen list:

(I don't think it has anything to do with 64 vs 32 bit, by the way.)

What you're looking for is  "VT"

Though the AMD stuff virtualizes a bit more, and performance is supposed
to be somewhat better, right?
Which AMD CPUs have virtualization?  I am having some trouble figuring out.
Recent models of the Athlon 64, Opteron and Turion. They used to call it
"Pacifica" but call it "AMD-V" now. I think AMD has a marketing issue. Xen
apparently supports AMD Pacifica since 3.0.2.
