So if I understand correctly you specify the option [dvipdfm] to  
beamer, which passes it on to pgf (which it loads) which passes it on  
to graphicx (which it loads), preventing you afterwards to call  
graphics with the [xetex] option (either explicitly or implicitly).

Did you try creating a symlink pgfsys-xetex.def to pgfsys- 
dvipdfm.def, and omit the option [dvipdfm] for beamer? This may be  
wildly wrong, but I imagine in that case pdfsys-xetex.def would be  
called for (and pgfsys-dvipdfm.def used in its place) and automatic  
driver detection would be used for graphicx (resulting in xetex.def  
being used).

According to its doc (I'm no beamer user myself), beamer accepts a  
[color={<color-option>}] option, allowing to pass on the option  
<color-option> to the color package when loading it. It's a pity no  
such mechanism exists for the graphicx package.
