That would do it, yes.  Good catch, Evgeni!  I bet this is the
"problem".

Newest thinkpad-acpi from ibm-acpi.sf.net has code that is supposed to
store the BT rfkill state across reboot and shutdown(!), please try
that and tell me if it works.  It will override the default_state with
whatever state BT rfkill was when you last rebooted/shutdown the
thinkpad.

This actually makes me wonder if I shouldn't add a knob to the rfkill
core to let the user order the rfkill core to *force* all rfkill
switches to block state even if platform drivers like thinkpad-acpi
request a different behaviout...
