Preview materials with alpha texture

Is there any way to preview my material with texture-controlled alpha in the viewport?

  • Textured mode - on.
  • GLSL - on.
  • Material alpha - 0
  • Texture with alpha gradient (from 0 to 1), Alpha influence is set to 1

Blender shows fully transparent object. I can see it only when select it and blender shows me its wireframe.
