This is not Nvidia's problem but just Chromium 10.0.616.0 which sucks this way:
When visiting HTML5 web page with Google Chromium 10.0.616.0 on PC with you will see message on console:
base/native_library_linux.cc(32)] dlopen failed when
trying to open libGLESv2.so: libGLESv2.so: cannot open
shared object file: No such file or directory
saying that OpenGL ES 2.0 library is not present.
It means only that dumb Chromium looks for libGLESv2.so on desktops system instead using libGL.
Firefox 4.0.b8 after toggling webgl.enabled_for_all_sites to true works great. Which is a proof that Chromium 10.0.616.0 is buggy
