Some Core Duo era ThinkPad models ship with Intel CPUs that implement VT-x for hardware-supported virtualization, but the capability is disabled by the BIOS. The only known solution is to flash a newer version of the affected ThinkPad's BIOS.
See this LKML thread for more information.
BIOS configuration
For some reason, VT-x is disabled by the BIOS on some ThinkPad models. Before you attempt a firmware update, you should check this article to confirm that your BIOS version has VT-x as a configurable option.
