A reader points out in the comments that the story is geting out and there is this article in the International Herald Tribune on the fraud that mentions a place in Valle de La Pascua where the votes were counted and did not agree. I have heard of this and two other cases but so far it was hearsay:
“CARACAS The perception that a massive electronic fraud led to President Hugo Chávez’s mandate not being cut short in the recall referendum on Sunday is rapidly gaining ground in Venezuela. …Evidence of foul play has surfaced. In the town of Valle de la Pascua, where papers were counted at the initiative of those manning the voting center, the Yes vote had been cut by more than 75 percent, and the entire voting material was seized by the national guard shortly after the difference was established.
