Hmmm, somehow (perhaps via xfs) your freeserif truetype font
is recognized as X core fonts.  Emacs' default fontset has
an entry for Cyrillic as below:

     (cyrillic (nil . "ISO8859-5")
	       (nil . "microsoft-cp1251")
	       (nil . "koi8-r"))

So, Emacs tries fonts of those registies in turn, and finds
that freeserif best matches with your requested font size.
And the ugliness is because the font is used as an X font;
i.e. antialias is not supported.

Should be.  And, in my environment, Emacs surely uses
"Clean" even if I start it as:
% emacs --font "Dejavu Sans Mono-8"

        character: д (1076, #o2064, #x434)
preferred charset: iso-8859-5 (ISO/IEC 8859/5)
       code point: 0xD4
           syntax: w 	which means: word
         category: Y:Cyrillic characters of 2-byte character sets c:Chinese
		   h:Korean j:Japanese y:Cyrillic
      buffer code: #xD0 #xB4
        file code: #xD0 #xB4 (encoded by coding system utf-8-unix)
          display: by this font (glyph code)
     -Schumacher-Clean-Medium-R-Normal--12-120-75-75-C-60-ISO8859-5 (#xD4)

I don't know why you have the different result.  I'll try to
add some debugging facility for font selection.
