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.
