Some chips for embedded market may tell you if they support OpenGL ES
and if so what version (for instance imageon 2300 lists OpenGL ES 1.0
compatibility in the marketing material).

I rather doubt anyone has a OpenGL ES driver for such "big" chips.

As Lars already told you, OpenGL ES doesn't really make sense for
"normal" PC.

No. Basically, OpenGL ES is a subset of OpenGL - throws out all things
rarely used to make the driver smaller/faster (for instance, color index
mode), as well as some features which are used often but require a lot
of code to implement (such as immediate mode, display lists). Read the
spec ( to see what's different to OpenGL.
