Your log file says "unknown chipset" because the kernel you're using doesn't have an entry for PCI ID 10de:0322. This is a harmless message. Further down in your log, you'll notice that it mentions that you have a GeForce FX 5200.
According to your X log, the NVIDIA driver is working fine. How are you determining that you have "no 3d acceleration"? What's the output of 'glxinfo'?
