for the mesh yoou have to add uv_vectors to the triangles, see 6.7.7.2.
Note to self: update syntax for mesh.

From your example, but with uv_vectors:
   mesh {
      triangle { 
         <0,0,0>,<3,1,1>,<6,0,0> 
         uv_vectors <0,0>,<1,0>,<1,1>
      }
      triangle { 
         <0,0,0>,<3,-2,0>,<6,0,0> 
         uv_vectors <0,0>,<0,1>,<1,1>
      }      
      scale 3
      translate 15*x
      uv_mapping
      pigment { Checkerboard }
   }
