I'm actually trying on a machine at work now, rather than the one I tried at home yesterday, but the results are the same.  This computer actually has as an Intel Core 2 Quad CPU (unlike yesterdays dualcore Xeon).  Is there someway to check if the processors on these machines support the virtualization extensions?

Most Atom CPUs don't support hardware virtualization extensions. AFAIK 
only the "desktop" variants support it.

No, it's the other way around: they are needed to run amd64 VMs, but 
32-bit host software can use them.
