As far as I know, recent thinkpad_acpi will save the last status of the
bluetooth rf-kill soft-switch in nvram on shutdown, and then restore it
on boot.

So, to be completelly correct (regarding /sys/ usage):
step 1)
 find the bluetooth rf-kill
 grep tpacpi_bluetooth_sw /sys/class/rfkill/rfkill?/name

step 2)
 set the desired state
 echo -n 0 > /sys/class/rfkill/rfkillX/state # is OFF
 echo -n 1 > /sys/class/rfkill/rfkillX/state # is ON
 (where X is what you found in step 1)

Doesn't this work for you? does Ubuntu have a vanilla thinkpad_acpi
kernel module?
