Regarding the airhopper paper at least, I found something pretty interesting from Markus Kuhn: http://www.cl.cam.ac.uk/~mgk25/pet2004-fpd.pdf http://www.cl.cam.ac.uk/~mgk25/pet2004-fpd.pdf "The two case studies presented in Sect. 4 and 5 analyze the compromising radio emanations first from a laptop LCD and then from a desktop LCD that is connected to its PC graphics card with a Digital Visual Interface (DVI) cable. In both cases, the video cable used to connect the display panel with the graphics controller turned out to be the primary source of the leaking signal."
