Ah, that's an issue not solved yet, I didn't realize that. I believe it 
should work to have EGL and GLES from our mesa_noglu. IIRC those are 
relatively thin wrappers around libGL, which will get chosen from 
/run/opengl-driver* due to LD_LIBRARY_PATH (BTW this variable is why 
often dlopening libGL works fine without any patching).

I don't think so. Driver is an OS thing, and I believe libGL 
implementation needs to be driver-dependent.
