Well, without shutting the system down, I did some poking about,
and added:

options agpgart agp_try_unsupported=1

to my modules.conf and lo, it did work. The improvement was large, 
at least from my initial testing:

(glxgears)		(no agpgart)		(with agpgart)
default size		160 fps			950 fps
fullscreen		 22 fps			139 fps

All are with 1025x768x32(24), AGPMode 4

I suspect that with more complete support of the chipset 
performance would be even better.

I have yet to try the Gatos drivers, but to make use of some of
the added features of the ViVo card (like ViVo) I suspect I will
have to do so.

Many thanks...
