I had tried this, but the result is wrong:

\documentclass{article} 
\usepackage[mag=1500,dvipdfm]{geometry} 
\begin{document} 
Hi 
\end{document} 

| This is XeTeX, Version 3.1415926-2.2-0.9995.2 (TeX Live 2009)
| ...
| *geometry detected driver: dvipdfm*
| ...

pdfinfo test.pdf:

| Page size:      1376.99 x 1781.99 pts

Correct (using pdflatex) is:

| Page size:      918 x 1188 pts

geometry should be fixed by detecting XeTeX directly.
At least it doesn't touch \pdf(h,v)origin if they aren't defined.
But
  *geometry detected driver: pdftex*
will remain confusing when running xelatex.

Otherwise driver pdftex is still the best choice, but
geometry must then be fooled about \pdfhorigin.

My proposal for geometry.cfg until geometry is fixed
(then use \@ifpackagelater):

% geometry.cfg with detection for XeLaTeX
% 2009-12-04 v1.1 Heiko Oberdiek
% 2006-06-07 Jonathan Kew
% Public domain
\ProvidesFile{geometry.cfg}[2009/12/04 v1.1 Configuration for geometry]
\begingroup\expandafter\expandafter\expandafter\endgroup
\expandafter\ifx\csname XeTeXversion\endcsname\relax
  % \XeTeXversion remains undefined
\else
  \PackageInfo{geometry.sty}{Using "pdftex" driver for XeTeX}%
  % XeTeX supports \pdfpagewidth and \pdfpageheight
  \Gm at setdriver{pdftex}
  % don't check this AtBeginDocument, just believe me!
  \let\Gm at checkdrivers\relax
  % However we have to fool geometry about the missing \pdfhorigin
  % and \pdfvorigin. But they shouldn't provided as count registers
  % globally all the time to prevent fooling others.
  \begingroup\expandafter\expandafter\expandafter\endgroup
  \expandafter\ifx\csname pdfhorigin\endcsname\relax
    \newcount\geometry at cfg@pdfhorigin
    \newcount\geometry at cfg@pdfvorigin
    \AtBeginDocument{%
      % being cautioness
      \begingroup\expandafter\expandafter\expandafter\endgroup
      \expandafter\ifx\csname pdfhorigin\endcsname\relax
        \let\pdfhorigin\geometry at cfg@pdfhorigin
        \let\pdfvorigin\geometry at cfg@pdfvorigin
      \fi
    }%
    \AtEndOfPackage{%
      \AtBeginDocument{%
        \ifx\pdfhorigin\geometry at cfg@pdfhorigin
          \let\pdfhorigin\@undefined
          \let\pdfvorigin\@undefined
        \fi
      }%
    }%
  \fi
\fi
\endinput
% End of file `geometry.cfg'.
