The more AGP memory you reserve for vertex arrays, the less memory is left for textures. So it should be not set to more than 1/2 of the AGP aperture size.

I'll be honest, I don't know much about the technical side behind this. 
Is this 1/2 memory idea a good rule of thumb? Wouldn't 1/2 of the cards 
memory be a better rule than the aperture size?

That command returns nothing for me.
