I tried older versions of Dolphin that still supported DirectX and it worked with the IZ3D drivers with every common setting including yellow/blue. IZ3D supports only OpenGL Stereoscopic that is quad-buffered. If quad-buffering is turned on within the OpenGL library it should be possible in Dolphin. The IZ3d driver does the dirty work of creating the stereo frames. This is possible with other OpenGL games like Unreal Tournament 3 which run openGL. This is something that needs to be brought to the attention of the Devs. I thought about posting it in the suggestions but that is 20 pages long and I am sure it will be little noticed. Here are some important websites for Devs if interested:
Here is a tutorial on implementing it in OpenGL libraries

Here is a link to Tridef which may be willing to write the code specifically for Dolphin. They have written code for many of the popular OpenGL games

Finally, IZ3D are very helpful on their forums and listen to their customers. I asked them awhile back to implement yellow/blue stereo and they released it in the following revision.
