This might not be what you had in mind, but preliminary PDF support has 
recently been added to version 3.7. Since it writes vector data as 
vectors, anti-aliasing is left up to the viewer. Adobe Acrobat Reader 
has an option to do it, for instance. If you use something like 
ghostscript or Illustrator, you could save to a raster format with 
antialiasing.

If you don't want to use a dev version, you can do the same thing with 
the mapserver 3.6 PDF support (try the shp2pdf utility).
