1. It is not expected, I have not removed /proc interface support for anything. Look at the thinkpad-acpi documentation, it is always (and I do mean ALWAYS) up-to-date.
The /proc interface for thinkpad-acpi is not going away for a while yet, unless ACPI itself decides that /proc/acpi must die.
2. The proper way to control ANY radio's rfkill functions is through the rfkill sysfs interface. That includes thinkpad-acpi's bluetooth and WWAN.
IOW, we may have a regression here. Please compile thinkpad-acpi with debug mode enabled, load it with the "debug=0xffff" and "experimental=1" parameters (as far as I remember, WWAN requires "experimental=1" to work, without that it will NOT load, and you will NOT get /proc/acpi/ibm/wan or anything else WWAN related from thinkpad-acpi), and send me the resulting log output from thinkpad-acpi.
