Laptop bluetooth button behaviour (bluetooth service starts on boot regardless)

When I press the bluetooth button on my laptop, bluetooth functionality toggles between active and inactive (that's a cool feature, thanks to the developers involved in getting that happening). However, when I reboot the laptop my previous bluetooth setting is lost and bluetooth is always active again.

What I would expect to happen is that my bluetooth settings are persistent (as with other devices and Other OS). I'm now using Kubuntu, I previously used Ubuntu and never notice the issue, so maybe it only applies to Kubuntu.

I don't know how this works, or what package is involved. If you can fill in the gaps that would be great. I've had this issue using Kubuntu 7.10-8.04. From what I recall, this issue didn't exist in Ubuntu 6.10-7.04. I'm using an ASUS A8J laptop. This issue may apply to other devices such as wireless, I've noticed that my screen brightness settings and sound volume settings seem to persist after a reboot (these devices also have similar physical buttons on the laptop, more reason to expect the bluetooth button to behave the same).

On a related issue, there is no apparent GUI to disable bluetooth. This means that your average user isn't going to know how to prevent this device from automatically starting on boot. I had to manually go in to the system services and disable the bluetooth service from running at boot in modes 2-5 to get the desired result. The problem I have with this method is that every time the system performs a major update I loose this setting as well.

This issue may relate to bug #35971.
