You're generally better off, I believe, doing an 'X -config-only' from a
shell, and then editing the resulting config file. Least, I've had more
success with that for most things...

You'll need to build a custom kernel with:
device agp
in the configuration file, this doesn't exist in the GENERIC kernel.
Or you can use "agp_load=YES" in /boot/loader.conf, and then you'll need
to reboot - I'm pretty sure that the AGP loadable module /cannot/ be
loaded after system boot, although I forget exactly why - I think it's
related to resource allocation which can only be done at a certain point
in the process.
Check /var/run/dmesg.boot for messages relating to 'agp' when the system
comes back up.
Then how well it works depends on how well (if at all) the i810 driver
from XFree86-4.2.1 will drive the i845, (which I have no experience of
as I don't own this chipset).
You may need to use the X server in VESA mode, or you may need to build
X from CVS - someone else can doubtless advise further.
HTH.
