I experienced such situation: a BIOS revision that did not expose any VT-
x options while the CPU supported them. A BIOS update solved it and a new
menu for VT-x was added to the updated BIOS.
But regardless this I think that "cpuinfo" is about CPU and not BIOS
capabilities; from here you can't really know what to expect.

Every motherboard manufacturer use different settings (even more for
OEMized motherboards that can be also highly customized by the computer
manufacturer), that's why is always better to directly ask them to be
sure :-)
