OK I'm getting closer. I found this thread
plop which lists like 8 drivers, and I think that I want to use the
AppleI386PCI (AGPGart for Intel):
This is the AGPGart driver for Intel provided by Tom H. It gives OpenGL gains, DVD playback and faster UI drawing, but still no QE/CI. Those are results for X1000 ATI cards... See Tom's post here.

AGPGart light (for intel ot other non-amd64 chipsets:
This is a very light version of my driver, the only thing it does is setting your card to 8X rate (4X for AGP2.0 boards), and showing as AGP of course. You can play with it to set fastwrites or change rate to 4X if you want, the source is included as always. This still doesn't improve the UI performance. Current registers configuration is the same for all chipset that follows AGP3.0 and AGP2.0 specs, which means every chipset will work, no matter if it's an AMD or Intel platform.\
I'm just not sure which...can you offer a suggestion?
thanks
