I think AMT needs to be provisioned on target computer to be exploitable.

There is also a local, non root user exploit to provision AMT described in Intel's announcement.

Yes. To be honest, Intel's announcement was a little dry, lacking details.

But to find out if it is, I need to go into the BIOS, right? Isn't it easier just to try going to a port?

[orblivion]

I keep reading that if you "disable AMT" in the BIOS (on my Lenovo, anyway) it just resets the settings. A complete WTF but that's what I've been reading.

Yea, maybe. going to the port is less conclusive in general case. E.g. you have some firewalls/other networking devices/etc in the middle that would deny access to that port and it would make you think it's disabled but it's actually not.
