Bluetooth annoyance

There's this minor bug in Ubuntu 9.0.4 where it doesn't permanently disable Bluetooth on my Thinkpad T60 everytime I boot up. It was quite annoying having to manually disable it from the "Bluetooth Preferences" window everytime I log in but I have found a way to resolve this.

1. Navigate to "/etc/modprobe.d/".
2. Edit the file "thinkpad_acpi.modprobe". If the file does not exist, create it.
3. Add this line.

options thinkpad_acpi experimental=1 hotkey=enable,0xffff8f bluetooth=disable
