i have exactly same situation as you! (GeForce FX 5500 and ubuntu 12.04 updated! (64bit) fresh install), and as i said, it just worked.
i just download NVIDIA-Linux-x86_64-173.14.34-pkg2.run and run it, asked me to create this /etc/modprobe.d/nvidia-installer-disable-nouveau.conf , after a restart and trying to disable mesa (replaced with nouveau) installed drvier and then it worked.
