r100/r200 only supports GL 1.3 and GLES1 1.1

One can easily check the above for any card, via glxinfo | grep
"Max.*profile version" ;-)

Hi,

not sure where this comes from, and I'm not sure it wouldn't cause the
below.

The attribute is EGL_RENDERABLE_TYPE, where the system has OPENGL and
OPENGL_ES, while Weston needs OPENGL_ES2.

Does this card actually support any kind of shaders? Maybe the Weston
build guide is mistaken there.

Weston's GL renderer supports only GL ES 2.0, which implies shaders.
You should still be able to get Weston running by using the weston
command line option --use-pixman, but that makes it software rendered.

If you have to use weston-launch, then the command would be:
weston-launch -- --use-pixman
