What graphics card is that, which radeon?

Could you try setting these environment variables for Weston:
export MESA_DEBUG=1
export EGL_LOG_LEVEL=debug
export LIBGL_DEBUG=verbose

That would tell us which radeon driver exactly loads. The kernel log does
mention "r200", but I don't know if that can support GL ES 2.0.

But if someone can say off-hand that this card won't support GL ES 2.0, then
that would be the cause. Weston does not have a renderer that would support
fixed-function GL. Then we could check if there is a way to make the error
message better.

I suppose 'glxinfo' output from X could give hints of the card capabilities,
too.

You could try with the weston command line argument --use-pixman, which gets
you DRM KMS but without OpenGL.
