The sonypi module has been (or will be) deprecated:

So it should probably not even be asked for in /etc/init.d/hotkey-setup - in any case, it just throws an error because the sonypi module is no longer included with the kernel.

At the moment, the hotkeys themselves are set up and send acpi events, but translating those events into actual hardware changes is where we get stuck (you can check this with tail -f /var/log/acpid ).
