Stencil Buffer on the Dell Axim X51v??

[gio]

I'm developing graphics applications for the Dell PDA's, specifically for the models with the Intel 2700G graphics accelerator (MBX based graphics hardware). According to the white papers on tile-based rendering published by PowerVR (who developed the MBX technology), stenciling is supported and it's certainly supported by OpenGL ES, but when I try to query for a config, I can't find out that supports a stencil buffer. Anyone have any idea if this graphics implementation actually supports stenciling? Also, I've had issues trying to read from the framebuffer using glReadPixels. Does anyone have any experience with graphics programming on these devices?
Thanks.

Did you take a look at Intel's white paper ?

It does says : Stencil operations will not return GL_ERROR even
though stencil operations are not supported

Thanks.

There is no stencil buffer on the current MBX models
