This modification of the above seems to work (namely, recognition of 
XeTeX based on \XeTeXversion being defined):

% Select an appropriate default driver
\begingroup
   \chardef\x=0 %
   % check pdfTeX
   \@ifundefined{pdfoutput}{}{%
     \ifcase\pdfoutput
     \else
       \chardef\x=1 %
     \fi
   }%
   % check VTeX
   \@ifundefined{OpMode}{}{%
     \chardef\x=2 %
   }%
   % check XeTeX
   \@ifundefined{XeTeXversion}{}{%
     \chardef\x=3 %
   }%
\expandafter\endgroup
\ifcase\x
   % default case
   \ExecuteOptions{dvips}%
\or
   % pdfTeX is running in pdf mode
   \ExecuteOptions{pdftex}%
\or
   % VTeX is running
   \ExecuteOptions{vtex}%
\else
   % XeTeX is running
   \ExecuteOptions{xetex}%
\fi
