That's a pretty bold statement. I have five x86 machines in my house currently being used, and none of them support VMX/SVM.
At least some Lenovo laptops disable VMX in the BIOS with no way to enable it. Some of the Core2Duo chips don't support VMX at all.
I think Xen without paravirtualization would be a serious degradation of usefulness.
