I did mount -o bind /chroot32/usr/lib /usr/lib32.
I saw i965 started loading, but loading crashed, because dynamic library loaded
found 64bit library for 32bit i965 -> something like "bad ELF" error.

See previous post please, what does LIBGL_DEBUG=verbose show? Try it with 64bit
glxinfo, so you see what to expect.

I think we are chasing the right library.
My output for LIBGL_DEBUG in 32chroot shows i965 loading. But when I start
32bit glxinfo in 64bit environment, I don't see any library loading.
You may still be right, because libGL.so may be used to load i965. But if libGL
doesn't find i965, libGL.so is still loaded.
