Hi William,
Did you try st_relate() the the appropriate DE-9IM matrix ?
I can't give you the pattern that will express your need exactly as I
read your email rapidely, but looking here may surely help:
http://postgis.refractions.net/documentation/manual-svn/ST_Relate.html
(also following the intersectionPatternMatrix link)
This presentation may also help:

I was wondering about that function. Unfortunately postgis 1.3
documentation doesn't have that handy link about the
intersectionPatternMatrix that's in the svn documentation.
I'll look at that, thanks.
