As usual, I had spoken too rapidly. Looking more closely, it seems all 
the work is done in teTeX's default configuration file 
/usr/local/teTeX/share/texmf.tetex/tex/latex/config/graphics.cfg, which 
contains code like:

% 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 %
   }%
\expandafter\endgroup
\ifcase\x
   % default case
   \ExecuteOptions{dvips}%
\or
   % pdfTeX is running in pdf mode
   \ExecuteOptions{pdftex}%
\else
   % VTeX is running
   \ExecuteOptions{vtex}%
\fi

So what could be done in this case would be to add code for automatic 
recognition of XeTeX, and have this modified graphics.cfg be inserted 
in /usr/local/teTeX/share/texmf.tetex/tex/xetex/ at the time XeTeX is 
installed.
