Pecisely identifying my processor.?

I want to install xp mode on my fresh installation of Windows 7 Ultimate. It is running on an Athlan 64 X2 4200+ and my motherboard is an Asus A8n32-sli. I did 'some' research on this and it seems that there are multiple different batches of 4200's...how do I tell the difference?

"Brisbane" (Energy Efficient 65W, G1 & G2, 65 nm)

All models support: MMX, SSE, SSE2, SSE3, Enhanced 3DNow!, NX bit, AMD64, Cool'n'Quiet,*** AMD-V **** So the Brisbane will run XP mode

[edit] "Windsor" (Energy Efficient, F2 & F3, 90 nm)

All models support: MMX, SSE, SSE2, SSE3, Enhanced 3DNow!, NX bit, AMD64, Cool'n'Quiet, AMD-V so will the Windsor.

[edit] "Manchester" (E4, 90 nm)

All models support: MMX, SSE, SSE2, SSE3, Enhanced 3DNow!, NX bit, AMD64, Cool'n'Quiet ???? However the Manchester does not support AMD-V.

Is there a way I can tell which one I have? I also looked around in the bios, and I don't see anything that even remotely seems to be AMD-V. I have a feeling that it is the manchester and simply won't support hardware virtualizatio, but......whatever, I guess I can still run a vm without hardware support. I could also upgrade the proc to something newer that would support it.

I appreciate any advice. TIA
