Thanks for your feedback, I always thought thinkpad_acpi driver was
managing all Thinkpad leds ;-)

Since then, I found that in
linux-source-2.6.31/drivers/net/wireless/ath/ath5k/led.c, some cards
are already recognized and known how they handle the wifi led : I'll
have to look with upstream ath5k devs how to update it for my Atheros
card model.

Not for me, I already remove the wifi driver when not using it, at
least to avoid energy loss !

I would say the contrary : echo -n '0' > /sys/... rf_kill/state to turn
the wifi off, isn't it ?
