XeTeX or XeLaTeX has no way of knowing the capabilities of the output  
driver you will use; it just generates (extended) DVI with references  
to the image files. So you won't get an error message from XeTeX  
itself or from the LaTeX macros if you use a graphics format that the  
driver doesn't handle; the only thing that can report this is the xdv- 
to-pdf driver itself.

Therefore, I think it will be best if the default xetex.def file  
shipped with XeTeX 0.997-based systems configures the LaTeX graphics  
package to recognize only PDF, JPEG, PNG, BMP, and EPS files, as  
those should work universally.

If Mac users want to run xdv2pdf and use additional formats, there  
could be an alternative graphics option to access this, but it will  
be the user's responsibility to select it; it won't happen  
automatically. Something like

   \usepackage[xdv2pdf]{graphicx}

could be used load a .def file that recognizes all graphics formats,  
when the default [xetex] option is restricted to the formats that  
xdvipdfmx supports.

By the time TeX Live 2008 ships, I hope all this will be more  
settled....
