For nVidia you can enable NV3x software emulation.

No, there's no such tool for ATI, and don't plan on using NV-Emulate for anything else than personal testing, cause performance especially for fragment shaders will be below any usable framerate (~1-2FPS).

You could try downloading and linking to Mesa for a software implementation of OpenGL.
