Is that a good validation test though? I'd have thought that if I programmed it to have a 50/50 chance that it would repeat the previous roll the graph would look about the same. i.e. half a million rolls look about the same as a million. Edit: which is to say that I thought the issue wasn't that the Intel/via chip's random number generators wouldn't look random in aggregate over lots of uses, but that people are concerned that there could be exploitable patterns in short sequences.
