A website has been created to compile information and links related to the issue: http://www.badmacbookprogpu.org/, in addition a video clearly demonstrate the video issue:
According to our information, Apple was not causing problems to unfortunate owners to exchange the defective motherboard, however, as the first MBP equipped with defective NVidia started shipping in June 2007, we are now 3 months over the warranty and Apple seems to behave suddenly differently according to some report, refusing to exchange the defective GPU for free. As NVidia already announced that it will cover the cost of repair, we are expecting now to have Apple issuing an extended warranty program for the affected models.
