[ltp] thinkpad-acpi (T6x/R6x/X6x): requesting testers for wireless switch behaviour

> 1. ThinkPad Model and BIOS version (dmidecode can tell you this)

ThinkPad X60s, model 17045UG, BIOS 7BETD2WW (2.13 ), EC 7BHT40WW-1.13 
no wwan here, just wifi and bluetooth.

well.. the BT led is off, dmesg says its off, hciconfig says its off, my
phone can't find it.. I'd say it's OFF.

No,
echo disable > /proc/acpi/ibm/bluetooth
status: disabled
echo enable > /proc/acpi/ibm/bluetooth
status: enabled

but it's still off

it's OFF

yep.

BT is off. 
Wifi is still off, but if I select a network from the networkmanager
list (that it remembered from before), it will wake up, dmesg will show
IRQ applied etc..

exactly, both the kill switch and /proc/acpi/ibm/bluetooth disconnect
the BT device from usb.
