I think the XeTeX community should align itself as closely as possible 
to the TeX community at large so that when the graphics package is 
updated, this would go without saying. I guess the appropriate action 
to take would be to add a bug report at latex-project.org to get it on 
their radar and post something along the same lines on comp.text.tex.

Is there anything extra that needs to be incorporated into the graphics 
package to ensure xetex functionality on par with, say, pdftex?
