Comment 2 for bug 397698

Opened a new task on the kernel package; it's not clear if the disassociation of the rfkill interface from /sys/class/net/$device/ is deliberate.

If need be, we can update this to look at /sys/class/net/$device/../../ieee80211/phy*/rfkill*/, but any time the kernel folks would like to settle on a stable interface would be just fine with me.
