Hi There,

  There are no module of generalization inside mapserver beside the 
filtering done on duplicate points at render time.
  What you shoud probably do is do the generalization of your data 
outside mapserver and only use mapsever to display diffrent data set at 
diffrent scales.
  I am not aware (I haven't really searched for it), of any open source 
tool that has all the generalisation tools. There are certainly 
softwares like FME that do have generalisation  module.
