Some machines throw acpi_wmi(4) events when those special buttons are
pushed.  Load acpi_wmi(4) driver and cat /proc/wmistat0.  The WMI
objects with hex numbers in the EVENT column *might* be for your keys. 
My HP Envy Sleekbook uses WMI for the radios key, but I haven't figured
out how to get events for the LCD brightness control keys (although my
brightness controls *do* work).  I used a Linux driver as a reference tho...

I'd like to make the acpi_wmi(4) interface easier to use, but my backlog
of contributions I'm sitting on is only growing.
