There is a big chance that your GL drivers were also misconfigured. The beauty about GLX is that you can use 'indirect rendering' which means that all 3D commands are sent to X which will then forward them to the correct 64-bit display drivers (or 32-bit display drivers). Each modern OpenGL driver accelerates indirect rendering these days. I guess that you lacked perhaps the right 32-bit dri module e.g. i965_dri.so for a x3100.
