检查VT-x是否被激活而不需要在Linux中重新启动?

I have a laptop with Intel Core i5 M 450 @ 2.40GHz which apparently has VT-x but not VT-d. I have Ubuntu 12.04 32bit but would like to have a virtual 64bit terminal-based Linux running on it. How do I know if the BIOS has this VT-x feature activated without having to reboot?I have a laptop with Intel Core i5 M 450 @ 2.40
