I believe agp video cards can snag system ram on an as-needed basis.  My
understanding of agp aperture is that it is how much of your system ram
can be allocated for use by the video card, if needed.  So a video card
with a large amount of ram should theoretically require less agp
aperture because it has enough on-board.  

As far as what it should be set at, beats me.  128 megs seems like it
should be plenty of video ram but I guess that also depends on how hard
you tax you video system.  Probably safe to leave it at its default.
