Works for me (GNU Emacs 24.0.50.1 (i486-pc-linux-gnu, GTK+ Version
2.12.12)), on Debian GNU/Linux Lenny. That's what describe-font says:

  name (opened by): -unknown-DejaVu Sans
  Mono-normal-normal-normal-*-9-*-*-*-m-0-iso10646-1
         full name: DejaVu Sans
  
Mono:pixelsize=9:foundry=unknown:weight=normal:slant=normal:width=normal:spacing=100:scalable=true
              size:  9
            height: 12
   baseline-offset:  0
  relative-compose:  0
