Well, digging this out of the archive.... 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?
