You have to hook up devd to get extra buttons that are not handled by 
acpi_asus(4).  One night, I wrote an ugly script to do that (attached 
for your reference).  To use it, you need to add the following lines 
in the /etc/devd.conf:

# ASUS laptop notified actions.
notify 10 {
        match "system"          "ACPI";
        match "subsystem"       "ASUS";
        action                  "/etc/acpi_asus $notify";
};

and place the attached file in /etc and make it executable.  For X.org 
OSD, you need to install ports/misc/xosd.

Enjoy,
