Although the suggested solution with bluetooth appears to work without further issues, there are still issues with regards to controlling the WWAN card. It is still fully functional, but it is not possible to turn it off the way it was done previously; as neither the suggested "/sys/devices/platform/thinkpad_acpi/wwan_enable", the legacy "/proc/acpi/ibm/wan" or anything resembling it appear to exist.
For further reference, there does appear to be a workaround to disable the radio in the modem: echo at+cfun=0 > /dev/ttyUSB0 (replace with first USB TTY of your modem) turns off the radio. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
