If there's a driver for your machine, acpidump or just watch 
/proc/acpi/events (and then port the driver to create an input device 
and use that instead). If there's no existing driver, you get to write 
one. There's no standard spec for sending hotkeys over ACPI, other than 
sleep, power and lid.
