Actually nvidia-glx-177 does divert /usr/lib32/libGL.so.1 to /usr/lib32/nvidia/libGL.so.1.xlibmesa. This is necessary since the NVIDIA driver has its own 32bit compatibility libraries which ia32-libs should not overwrite.
I'll see if I can make ia32-lib and the NVIDIA driver coexist with some patches (for both packages).
