It needs to be located as well. I have tried BIOS settings. My BIOS supports 3 States "enabled", "radio off" and "hidden". Changing these settings also changes 0x03, 0x24, 0x31, 0x3a and 0x84. But 0x48 still changes according to my patch. So it can at least be used to read the physical state of the switch, no matter what is set in the BIOS. I think that this physical state is important on models with a HW switch. When i enable the killswitch bluetooth is deactivated but ibm_acpi bluetooth/state might still show enabled. If one wants to know "is bluetooth ready for use?" the HW switch and bluetooth state have to be considered. I found that 0x48 & 8 is true when bluetooth is enabled and killswitch is disabled.
