I haven't followed this thread closely, but considering automatic  
driver selection: it might be nice to add another check for XeTeX  
<http://scripts.sil.org/xetex/>, based on \XeTeXversion. For example,  
the adapted color.cfg for XeTeX contains:

% Select an appropriate default driver
   % check pdfTeX
   % check VTeX
   % check XeTeX

In that case, for the geometry package the appropriate option would  
be dvipdfm, since the latest versions of XeTeX support the dvipdfm  
papersize \special.
