Not sure that makes sense to me; maybe I'm forgetting something.

That may be why NvAGP overrides to "3".  Using "NvAGP" "1", but
compiling the drivers with WITH_FREEBSD_AGP should be mutually
exclusive.  One tells the driver to use the NVidia AGP, the other
tells it to use the native FreeBSD AGP.  Like I said, you need to pick
one.  The NVidia AGP is probably the better choice.  You mention below
that it's already removed from the kernel, but that doesn't make sense
if you're getting the agp0: console output.  I'm assuming the kernel
was rebuilt since that config was commented out, but is that config
the one that was used?

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 do you get from the command kldstat?
