Those schematics have been floating around for some time. They didn't 
use any PCIe signals on the mini-PCIe connectors. USB and SDIO only.

I'm not sure why the schematics are so secret anyway. The cold war is 
over and the new boogie man is "terrorists". Maybe somebody paranoid 
missed the memo? What is somebody going to do, design a tablet that they 
can't buy the Tegra for anyway and take over the IMF or Wall Street?
