The fontspec version shouldn't matter, as finding fonts is handled by  
xetex itself. (I haven't updated to Will's latest release yet,  
either, but will include it next time I package things.)

I've tried GFS Didot (both the .otf and .ttf releases -- which are  
you using?) on my SuSE 10 system, and so far I haven't seen this  
problem; I get the expected faces, and the Greek characters appear  
fine. But I suspect there's a certain element of (unwanted)  
randomness going on here, especially as Ralf reports different  
results with the two versions of the family name.

Looking at the font files, the names "GFS Didot Rg" and "GFS Didot"  
should both work, as all faces provide both these family names  
(though I would say "GFS Didot" is preferable). And the style  
information seems reasonable, so xetex should be able to find the  
regular, bold, italic, bold-italic versions correctly, regardless of  
which family name you give.

Pablo, what Linux distro are you using, and did you install a binary  
xetex package (if available for your system), or compile from source?

I wonder if there could be an issue with fontconfig and/or freetype  
library versions that could explain why we see different behavior.  
Could you check what versions you have installed?
