It can be powered, since in the X60 the WWAN port only has the USB lines wired, so it's not much of a security problem for the PCI bus as long as it is not connected to the USB bus where it could wake up from suspend and pretend to be many different things.
The hardware swich properly disconnects the bluetooth module from USB. It would be nice to do the same for wwan, but I guess ec_access and echo -n "suspend" are better than nothing. I plan to try and create a rfkill-wwan kernel module doing just that. I tried to find some code example for the RCBA but couldn't.
Has anyone ever managed to get the USB lines on the T60 WLAN slot to work? I plugged in an Intel 7260 802.11ac + Bluetooth card, and it is reportedly using USB for bluetooth and PCIe for WLAN. My problem is that the Bluetooth part of the card doesn't even show up in lsusb.
This thread made me wonder whether this is just an issue with broken rfkill.
