Graphicx and xelatex

Hi all,

I've just upgraded to tex-live 2007 and decided to play with XeLaTeX.
After some work I've managed to get the fontspec package working with
my supposedly unicode text. Problem now is that I can't get graphicx
to load any pdf or eps figure to the document. PNG works, but then it
is rasterized. I've tried loading graphicx with xetex and dvipdfm
options, to no avail. What am I missing here?
