the v.random.cover addon script for grass 6 exists to do that.
http://grasswiki.osgeo.org/wiki/AddOns/GRASS_6#v.random.cover
'' v.random.cover is a shell script for creating random points constrained
within an irregularly shaped vector area. (v.random places points only in
current region rectangle). Optionally the user can upload raster values at
the points. See also 'r.random cover= vector_output=' ''
It's internal method is not especially efficient, but it gets the job done
all the same.
