I'm just finding this after coming back from a few days of holiday.

What I did is putting in ~/Library/texmf/tex/xetex/config/ slightly 
modified versions of color.cfg and graphics.cfg, as follows:

- For graphics.cfg:

This is especially useful for packages that load automatically the 
color and/or graphics packages, without letting the user specify the 
option explicitly. (The beamer class might do this, if I remember well 
-- not sure though.)

That said, given the texmf/tex/xetex directory is, I think, only 
searched when using XeTeX, the above is probably unnecessary and you 
only need to create files ~/Library/texmf/tex/xetex/config/color.cfg 
and ~/Library/texmf/tex/xetex/config/graphics.cfg containing the single 
line:

> \ExecuteOptions{xetex}

What indicates that texmf/tex/xetex is only searched when using XeTeX? 
The lines (edited for clarity)
