On Panda the +5V supply for DVI EDID is supplied by the same regulator that poweres the USB Hub. Currently, the DSS/DVI subsystem doesn't know how to manage this regulator and so DVI EDID reads will fail if USB Hub is not enabled. As a temporary fix we keep this regulator permanently enabled on boot. This fixes the DVI EDID read problem.
