Hmm...apparently NVAGP couldnt be loaded, one reason is that maybe agpgart 
is compiled into your kernel statically, or else it is as a module which 
is preloaded even before X starts.

So what you can do is to try and rmmod it before X starts and see if the 
option 1 forces nvagp.

But it is very strange as how you got such a high framerate with agp 
disabled :(

I will run glxgears on my box and come up with my benchmarks, I dont have 
access to it at the moment.

Let me see what the framerates are for glxgears with various AGP options 
in my computer, and I will getback to you.
