Obvious bugfix: Shazam intercepts all video port accesses and keeps a record of the current state of the video card at all times. It therefore has a definate knowledge of the current state of the video card at all times...
Linus: Am I correct in thinking that the required facilities to do suchlike are already in the kernel...
