  I thought your posting was the most interesting one I saw on fedora-list, and 
I have been hoping someone would provide an answer.  This is a problem with 
proprietary programs compiled elsewhere and distributed as binaries but also 
some pure open source programs (firefox and HelixPLayer for example) that I 
cannot compile in 64-bits at this point.  Does anyone know a way to help 
firefox, its plug-ins, and other programs compiled in 32-bit kernels but running 
on FC2 x86_64 to find the bluecurve theme and the 32-bit gtk/gdk modules they 
need?
