afaik you have to get a E8xxx series CPU or Xeon E3110/L3110 if you need Intel VT.
i´m in the same boat here, looking for a CPU with VT support - other series like the E7xxx, E5xxx etc. don´t support Intel VT
and VT will be a requirements to use functions like XP Mode in Windows 7. (which is the best function by far that microsoft has ever given the users).
