Which Fn-Fx combinations produce ACPI events depends on the bit mask in
/proc/acpi/ibm/hotkey.

I wanted to bind a script to Fn-F6 (to toggle Bluetooth on/off
separately from WiFi), so I had to edit
/etc/modprobe.d/ibm_acpi.modprobe on my Ubuntu system and change it to
read

  options ibm_acpi hotkey=3Denable,0xffff experimental=3D1

(IIRC the experimental=3D1 bit was already there).

So, one way of doing this is to change the hotkey bit mask, and write a
script that uses radeontool (or echo video_switch > /proc/acpi/ibm/video).
Another way, probably, is to use the bioshotkeys option in xorg.conf.
