You wouldn't happen to know exactly what rfkill mechanism the modem
firmware means by 'BIOS'?  And what about 'GOBIIM'?

As your example shows, 'W_DISABLE' was the only external LPM input of
the older 77xx modules ('User', 'Temp' and 'Volt' are all modem firmware
internal). And 'W_DISABLE' is simply pin 20 on the mini-PCIe connector,
usually controlled by the laptop rfkill circuitry.  You can override
that with a piece of tape if necessarry.

I assume the new signals must be software interfaces, maybe some magic
shared config register or some sort of USB control message?  But that
should also be documented in a spec somewhere. It is part of the
mini-PCIe host/device interface even if it is software based.
