Problems with stencil - Renderbuffer

Any body try to Create
Renderbuffer for stencil data on nvidia’s hw?!
:
glBindRenderbufferEXT
( GL_RENDERBUFFER_EXT
, m_stencil_buffer
);
glRenderbufferStorageEXT
( GL_RENDERBUFFER_EXT
, GL_STENCIL_INDEX8_EXT, m_width, m_height);

//last is fail !!!

Stencil buffers are AFAIK not yet supported. This is because stencil buffers are packed together with depth buffers on current hardware. And there is no STENCIL8__DEPTH24 format defined. But I read somewhere that the ARB is working on that.

Thanks…
Even nvidia’s GL_NV_packed_depth_stencil can’t help here :frowning: . Waiting for miracle from ARB, as usual…
