I think in woody the first problem is FreeType.
I have tried to backport freetype, fontconfig and xft to woody. But freetype in woody is 2.0.9, and many packages depend on it. And if you force to upgrade it, some dependence will fail (they require freetype (=2.0.9)), and some packages will not work (e.g. OpenOffice.org woody backport is known to be broken with freetype 2.1.4).
So I think it's nearly impossible to backport these font packages to woody... 8-(
