Stereo buffer

I noticed in SIrrlichtCreationParameters, that there was a stereo buffer option. It said it would try to create stereoscopic output. Does that mean that the game will run in 3D on certain monitors? or with nVidia 3D glasses?
And if so, will the DirectX9 driver get that?

No, it means that you can use an expensive OpenGL card, which has stereobuffers, and render to two separate stereo buffers the whole scene. The card will then take care of properly providing the stereo images to the user.
For the NVidia driver, you just take the usual non-stereo app, enable stereo in the driver, and use whatever glasses you need.

Oh, so irrlicht can render in 3D, cool. Where is it implemented in the OpenGL driver? And is it possible to do in DirectX9.

No directx has no stereo buffers. You can simply render to the left and right framebuffer. There are specific render targets for this purpose.
