How relevant is the following change to this mystery?  This is an 
excerpt from a diff of AbstractJdbc2Statement between the versions we've 
been discussing, specifically, the internals of the setDate(int, Date, 
Calendar) method:

2006-11-05 00:44:44.000000000 -0500

I mean, it obviously explains where the unspecified type is coming from, 
but how likely is that to trigger the FE/BE type mismatch we're seeing 
many records later?
