Just read through the other thread on Satoshi Nakamoto and clicked the link to the book "Electronic Payment Systems for E-commerce"; if the picture of the author on that page is correct (which from the page here:
http://65.54.113.26/Author/1718958/donal-o-mahony, it is) I'm afraid that Donal O' Mahony the author and Donal O' Mahony of Davy are two completely different people, which puts paid to the idea that Donal O' Mahony of Davy is Satoshi.
