If the hole is defined mathematically, you can use pixel shaders to clip() pixels that you don't want rendered. If it's defined by an artist, texturing is probably the way to go, combined with alpha blending or alphakill.

Since you have to define the polygon in terms of triangles anyway, just make a few more triangles to define the shape with the hole in it.
