thinkpad keys T520

[Sean Bruno]

the Fn key seems to send the system the same key command as the power
button *should* send.  This leads to many problems on this machine.

How can I start tracing code the key strokes for keys that are not the
normal keyboard keys?  e.g. the Fn key or vol up/down and the power
button?

If I load acpi_ibm(4), it doesn't seem to ever get used so I am confused
as to where to start.
