I've recently changed fontconfig to use the OS/2 table entries for weight 
to provide more accurate weight values to applications.  That should let 
applications (and users, presumably) see finer gradations in weight.

You'll still be limited to the weights available in the fonts you have; 
fontconfig can only show what's present.
