If you look further down, the Geforce 3 should do it in hardware.
This python script will print the list of extensions supported by your 
hardware to the console.  You need GL_ARB_shadow & GL_ARB_depth_texture:

from Blender.BGL import *
print glGetString(GL_EXTENSIONS)

Make sure:
1. Shadows are enabled for the scene ("Shadow", Render Panel in scene buttons)
2. Shadows are enabled for the light ("Buf Shadow", Shadow & Spot panel in 
light buttons)
3. Clipsta & clipend are set correctly.  The shadows look better the closer 
they are to the near clipping plane.
4. Only Spot & Sun lamps support shadows. (Point lights require 6 extra passes 
and 6 textures - you can't use more than 4 textures without pixel shaders on 
Geforce FX class hardware)
Sun lamps are a pain because they have an orthographic projection.  Scale the 
lamp to get a bigger shadow area.  Evil I know.
5. Faces have the Light mode set.
