There are several threads in the archives of acpi@ and mobile@
discussing this. Most things are pretty easy. Use xev to find the
events generated by the volume buttons. Mute and the ThinkLight (if
your system has one) should work as is.

Brightness is a bit bigger issue as Lenovo has completely revamped it
These buttons don't generate events. :-( You can install the acpi_call
port and use it to set the brightness, but it is a pain as it does not
allow for setting incremental changes, only absolute values.(16 of
them).

Google for "FreeBSD acpi x220 notes". That should find the thread with
the details.
