[ltp] Wlan led with 2.6.31

[Frédéric Boiteux]

  I've gone further with my WLAN led problem, discovered that :
- when the Thinkpad starts, it's not lighted
- it is lighted when writing in /sys/class/rfkill/rfkill*/state (rfkill
for the wifi card), either writing 0 or 1.
- once lighted, I don't know how to shut off

Does your wlan led is working right on your thinkpads ? do you know
which part of the system is handling it ? Thanks for any tip !
