Yeah, I'm not sure of the exact details of the implementation, but
when it's enabled it captures TCP port 16994 and amtterm on another
machine connects to the serial port AMT provides (e.g. /dev/ttyu2).

To use it I set the following in loader.conf:
comconsole_port="0x50b0"
hw.uart.console="io:0x50b0,br:115200"

It was a bit awkward to configure -- here are some notes on the steps
I had to take:

- F1 at boot to enter X220 bios and enable AMT
- Ctrl+P at boot to enter AMT configuration
- Default password is 'admin'
- New password has annoying requirements for case/numbers/punctuation
- I could not get DHCP to work; I assigned a static address separate
from the one used by the OS
- I couldn't get it to work until I enabled legacy redirection
