A snippet of code for my game I'm working on:

glGenRenderbuffersEXT(1, &scene_depth);
glBindRenderbufferEXT(GL_RENDERBUFFER_EXT, scene_depth);
glRenderbufferStorageEXT(GL_RENDERBUFFER_EXT, GL_DEPTH_STENCIL_EXT,
                         scene_width, scene_height);
scene_stencil = scene_depth;
...
glBindFramebufferEXT(GL_FRAMEBUFFER_EXT, scene_fbo);
glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_COLOR_ATTACHMENT0_EXT,
                          GL_TEXTURE_2D, scene_tex, 0);
glFramebufferRenderbufferEXT(GL_FRAMEBUFFER_EXT, GL_DEPTH_ATTACHMENT_EXT,
                             GL_RENDERBUFFER_EXT, scene_depth);
glFramebufferRenderbufferEXT(GL_FRAMEBUFFER_EXT, GL_STENCIL_ATTACHMENT_EXT,
                             GL_RENDERBUFFER_EXT, scene_stencil);
glViewport(0, 0, scene_width, scene_height);

...on my nVidia Geforce FX 5500 card, and it works perfectly.
