I don't think you'll be able to do it with XeTeX at present, as  
there's no mechanism for you to get a /ToUnicode resource into a PDF  
generated through Quartz by xdv2pdf. (Short of post-processing the  
PDF with some utility you devise, I suppose - which is how I did the  
hyperref stuff, after all.)
