I figured out why NvAGP 1 "fixed" the problem. It seems that the tc1100's AGP host bridge is in fact unsupported by the NVIDIA AGP driver, so when we force the NVIDIA driver's AGP mode, we effectively disable AGP and only use PCI. I wonder if kernel AGPGART is not doing some sort of appropriate AGP magic before the NVIDIA driver comes back up? joshua ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
