Using emacs-snapshot-20090207, the text display becomes very ugly when
set via:
(set-default-font "DejaVu Sans Mono-10")
However, if the font is set via the menu bar: Options->Set Default Font
then the fonts look good (i.e., with proper anti-aliasing).

Hi Handa-san,
I think we should give the xft font backend (where it is available) a
higher priority than the x backend; otherwise, users will keep
experiencing bugs like this.
WDYT?

Stupid question --- is there a way to force the right thing to happen
from emacs-lisp? My biggest gripe is that I couldn't figure out a way
to make the right thing happem from my .emacs.el file, despite a lot
of time spent trying to find the right interfaces via M-x apropos. So
at the moment, I'm firing up emacs, and then having to use
Options->Set Default Font from the menu bar to change to a small font
size. (And I'm an old-school emacs person who normally would run with
the menu bar and tool bar disabled. :-)
I suspect the correct default though should be to give the xft font
backend a higher priority; especially at the moment, where many people
are using emacs-snapshot *because* of the nicer font display.
Thanks, regards,
- Ted

Something like this will do the trick:
(set-frame-parameter nil 'font-backend '(xft x))

I at first want to figure out why the above two methods for
seting a font are different. At least, I can't reproduce
the difference. Can you? When I have "dejavu sans mono"
fonts both for fontconfig and X as below, both methods set
the default font to X font.
% fc-list 'dejavu sans mono'
DejaVu Sans Mono:style=Bold Oblique
DejaVu Sans Mono:style=Oblique
DejaVu Sans Mono:style=Book
DejaVu Sans Mono:style=Bold
% xlsfonts '*-dejavu sans mono-*'

I do see this bug.
I have 'Emacs.Font: Monospace 9' in my .Xresources file. With
`emacs -Q', C-u C-x = reports the font as
xft:-unknown-DejaVu Sans
Mono-normal-normal-normal-*-12-*-*-*-m-0-iso10646-1 (#x1E)
If I then do
M-: (modify-frame-parameters (selected-frame)
(list (cons 'font "DejaVu Sans Mono 9")))
the font becomes non-antialised, and C-u C-x = reports
x:-dejavu-dejavu sans
mono-medium-r-normal--12-87-100-100-m-70-iso8859-1 (#x3B)
My results for fc-list and xlsfonts are the same as yours.

If the frame is already using an XFT font, doing
(set-face-attribute 'default (selected-frame)
:font "DejaVu Sans Mono 10")
will give an XFT (anti-aliased) version of DejaVu Sans Mono. If the
frame is using an X font, the same code gives the X version of DejaVu
Sans Mono.
Doing
(modify-frame-parameters (selected-frame)
(list (cons 'font "DejaVu Sans Mono 10")))
always returns the X version. This discrepancy is due to the use of
font_open_by_name instead of font_load_for_lface.
I don't think there is anything that need to be corrected, apart from
giving the XFT driver a higher priority; I've just done that.
