Where is this font coming from

[Harry Putnam]

Setup is on Gentoo linux with emacs version:

  GNU Emacs 24.0.50.1 (i686-pc-linux-gnu, X toolkit, 
  Xaw3d scroll bars) of 
  2010-05-22 on reader

I've been fussing with emacs fonts for a few days.

Now even when I start with emacs -Q .

When I look at the font in use with `C-u C-x =' I see a rather hefty
font and even has the character set locale type wrong for me... mine
should be -iso8859-1, 

what I see is 
-unknown-DejaVu Sans Mono-normal-normal-normal-*-20-*-*-*-m-0-iso10646-1

Where is it getting set?

My .Xdefaults/.Xresources shows:
emacs*font: -dec-terminal-bold-r-normal--14-*-75-75-c-80-iso8859-1
