Well, today it doesn't, could be yesterday it also did not, although  
I remember that with the more complicated original file I had to use  
xelatex with -shell-escape once one of the days before yesterday ...  
and then I saw the XBB file, which motivated me to produce the BB  
file manually. More details and LOG files can't be recalled, and on  
Tiger no TimeMachine, or VMS versioning system, is available ...

The LOG files show that

	/usr/local/texlive/2008/texmf-dist/tex/xelatex/xetex-def/xetex.def

or

	/usr/local/texlive/2008/texmf-dist/tex/latex/dvipdfmx-def/dvipdfmx.def

are used when using no option or the [dvipdfmx] option. But, as  
explained to Bruno, in Emacs' shell I could have been in elder  
release ...


Anyway, when I courageously deleted the *BB files, the image size was  
correct again. And I was not able to persuade XeTeX again to produce  
the XBB file, as described to Bruno. Regenerating the BB file on the  
command line and running xelatex again I had the small image again.  
When using the [dvipdfmx] option the image size remained correct,  
also when the BB file was present. The presence of the XBB file had  
never, in no case, an influence on the image's size.

So the reason for the small size is finally found! Explanation still  
missing (both Mac OS X output drivers make the small image appear  
when no option to graphicx is passed at its load time and the BB file  
exists).
