Ah.  WLAN LED works for me (kernel 2.6.27-7-generic, iwl3945 version
1.2.26ks), but I hear you anyway.

I've configured Fn-F6 as the Bluetooth toggle key:

    # /etc/acpi/events/ibm-bluetooth
    # This is called when the user presses Fn-F6 button and calls
    # /etc/acpi/bluetooth.sh for further processing.

    event=3Dibm/hotkey HKEY 00000080 00001006
    action=3D/etc/acpi/bluetooth.sh

and

    #!/bin/bash
    # /etc/acpi/bluetooth.sh
    # Enable/disable builtin Bluetooth on IBM Thinkpads

    if grep -q enabled /proc/acpi/ibm/bluetooth; then
        echo disable > /proc/acpi/ibm/bluetooth
    else
        echo enable > /proc/acpi/ibm/bluetooth
    fi

At one point I also had to fiddle with the thinkpad_acpi hotkey mask to
get Fn-F6 to send an ACPI event, but it doesn't seem to be necessary any
more in Ubuntu 8.10.
