I even cvsupped world and rebuilt, and now nvidia.ko doesn't try the agp0 stuff. I guess that's progress, but AGP still doesn't work. > Then you should definitely not be compiling the drivers with > WITH_FREEBSD_AGP. Try recompiling without that config. Linux support > is probably not a problem, so don't worry about that. What would the NvAGP "3" option do, then, if it couldn't fall back on nvidia's agp implementation? I supposed it could do both if you built with WITH_FREEBSD_AGP. Oh well, it's gone now. > What do you get from the command kldstat?
