jQuery.noConflict(); won't work with 1.3.2

jQuery.noConflict(); won't work with 1.3.2

Hello,
I'm using jQuery 1.2.6 and I need to upgrade to 1.3.2
I have to use jQuery.noConflict(); because we are using JSF ICEFaces and there is a confclit. noConflic works fine in 1.2.6 but did not work in 1.3.2

Has anyone had a similar issue??
