What system are you rinning (i.e. Gnome, KDE, other?)?
Does
% xrdb -query|grep Xft
show anything?

How about
% xdpyinfo|grep resolution
?

Emacs now uses the DPI setting from the dekstop settings if available instead 
of the dpi reported by the X server.  You probably have a mismatch there.

Get a new version from the trunk and get the value of the lisp variable 
xft-settings (C-h v xft-settings).

It is not the weight, it is the hinting.  Emacs uses the values from the 
desktop settings if available, or the fontconfig defaults otherwise.
