Problem Description: most features of sony-laptop are infunctional

Steps to reproduce:

Though wwan is powered on:

0
Echo has no effect either.

Bluetooth:
[r...@pygmytarsier ~]# hcitool scan

[r...@pygmytarsier ~]# cat /sys/devices/platform/sony-laptop/bluetoothpower 
255
[r...@pygmytarsier ~]# echo 0 >
/sys/devices/platform/sony-laptop/bluetoothpower

        00:1B:59:4C:6B:E8       M600i
[r...@pygmytarsier ~]# cat /sys/devices/platform/sony-laptop/bluetoothpower 
0

[r...@pygmytarsier ~]# cat /sys/devices/platform/sony-laptop/fanspeed 
17
[r...@pygmytarsier ~]# echo 10 > /sys/devices/platform/sony-laptop/fanspeed 
# no event messages
[r...@pygmytarsier ~]# cat /sys/devices/platform/sony-laptop/fanspeed 
17

Shouldn't there also be wlanpower?
[r...@pygmytarsier ~]# grep . /sys/devices/platform/sony-laptop/*
/sys/devices/platform/sony-laptop/PID:13
/sys/devices/platform/sony-laptop/bluetoothpower:0
/sys/devices/platform/sony-laptop/fanspeed:17
/sys/devices/platform/sony-laptop/modalias:platform:sony-laptop
/sys/devices/platform/sony-laptop/uevent:DRIVER=sony-laptop
/sys/devices/platform/sony-laptop/uevent:PHYSDEVBUS=platform
/sys/devices/platform/sony-laptop/uevent:PHYSDEVDRIVER=sony-laptop
/sys/devices/platform/sony-laptop/uevent:MODALIAS=platform:sony-laptop
/sys/devices/platform/sony-laptop/wwanpower:0

FKeys/PKeys [Fn]+FXX (brightness, vga, zoom) and 2 of the PKeys (S1, eject)
don't work either.

sony-laptop seems to register a JogDial device which I don't have (at least as
far as I can tell).
