Binary package hint: devicekit

I'm using nouveau as xorg driver. The driver manage properly backlight,
I can change it from the power management plasmoid (on kde), but fn keys
are not working

using acpi_listen, 
brightness down is giving :
sony/hotkey SNC 00000001 00000010
sony/hotkey SNC 00000001 0000003b

brightness up  :
sony/hotkey SNC 00000001 00000011
sony/hotkey SNC 00000001 0000003b


in dmesg, I've seen the following, I don't know if it is linked :
ACPI: EC: missing confirmations, switch off interrupt mode.
