Yes (http://www.overcomingbias.com/2008/01/newcombs-proble.html). Bearing in mind that my setup is unusual, the following two paragraphs explain:

There is a large literature on the topic of Newcomblike problems - especially if you consider the Prisoner's Dilemma as a special case, which it is generally held to be.  "Paradoxes of Rationality and Cooperation" is an edited volume that includes Newcomb's original essay.  For those who read only online material, this PhD thesis (http://w3.ub.uni-konstanz.de/v13/volltexte/2000/524//pdf/ledwig.pdf) summarizes the major standard positions.

I'm not going to go into the whole literature, but the dominant consensus in modern decision theory is that one should two-box [corresponding in my version to returning the blank paper], and Omega is just rewarding agents with irrational dispositions.  This dominant view goes by the name of "causal decision theory".
