That unfortunately seems to be the consensus. At least one of our card
vendors believes it's a firmware and not an EEPROM setting issue (waiting to
hear from the other). They're attempting to resolve it through Qualcomm.  I
have doubts there's going to be a resolution any time soon... Thanks much
for the advice!

At least 10.1.467 era firmware ignores some of the OTP settings, so you may
have to go poking in the firmware source to be certain of what can be
configured and/or fix the limitations.

Thanks,

the otp.bin firmware file? Is there a mapping of the OTP to EEPROM settings
available? That would be an easy fix if I can make a modification there to
activate RFKILL.
