I figured it out eventually and it was my fault: I had the ft-smooth
patch applied over freetype 2.1.3 and I suspect it was never meant for
non-AA; that's what made fonts ugly at small sizes. Freetype 2.1.4 with
the bytecode interpreter performs great with the AA off under size 12.

AA off, hinting on, autohinter off for everything and the AA turned on
again over 12. This is what I was looking for.
