P&J Powers = Queen Visit?

Bertie Ahern has linked the devolution of policing and justice powers to a visit by the Queen to the Republic. The RTE report states:

“Bertie Ahern says that if the issue of policing was completed in Northern Ireland, and it was scheduled to be in the short term, then he said the Government could put its mind to considering the issue seriously.”

A visit in 2008 was also ruled out. Why bother linking the two, it hardly has any leverage factor?
