I think that there is still something wrong somewhere. I know that glxgears is not intended for benchmarking, but, I would say your card should read alot higher than that. As you have seen, my GF4 MX440 runs around the same level. Your card being a FX5200, it should be alot higher (I'd say around the 1500fps mark at least). Sounds like a library problem somewhere.
I run a GF FX5950 Ultra at home, and the glxgears' output is around 8700fps+.
Also make sure that you run the nvsettings utility to activate those settings. As when you shutdown the system and/or reboot. These settings will not take effect until you re-run nvsettings again.
And in some cases I found the agpgart driver to run a little faster then using Nvidia's, so that maybe worth looking into.
