All Pentium and Celeron processors have numbers below 6000, so
they fit in the rule of thumb I gave above. The Celeron 900
is listed as having VT on the processorfinder, but that also
incorrectly lists it as having two cores, so who knows?

These are the ones I listed above as 'may have VT':
Q8300, E7400, E7500, E5300, E5400. The link I gave was to another
article mentioning these exact numbers. The E7300, Q8200 and Q8400
I listed as 'Doesn't have VT' are the remaining ones E7xxx and Q8xxx
processors, which appear to be phased out (not sure about Q8400,
which was announced at the same time as this news).
