I'm assuming you have the nvidia-driver port installed? Text below is
from /usr/X11/share/doc/NVIDIA_GLX-1.0/README.
hint.agp.0.disabled="1"
If you're using FreeBSD 5.2.1 or another -CURRENT kernel that
does not yet
offer this functionality, the following patch will enable it:
/usr/X11R6/share/doc/NVIDIA_GLX-1.0/agp.ko-hints.diff
My 5.2.1-RELEASE-p4 didn't support it without patching, I'll have to
check but I don't think I used it in the end.
Does your XF86Config contain the following entries in 'Section
"Device"':
Driver "nvidia"
Option "NvAGP" "1"
I'm pretty sure this (the 'Option "NvAGP" "1"') is what did it in the
end for me. If it doesn't appear to work, don't forget to verify which
config X is using by checking your XFree86.0.log or :0.log for the line:
(==) Using config file: "/etc/X11/XF86Config"
