Xorg can't find my graphics card

[Ross Gohlke]

I have successfully installed FreeBSD7.0-RC1 on a 733MHz G4 tower w/ CD-ROM:
http://www.everymac.com/systems/apple/powermac_g4/stats/powermac_g4_733.html

I was encouraged by Peter Grehan's report of getting Xorg working on a
computer with the same graphics card (GeForce2 MX) as mine:
http://wiki.freebsd.org/powerpc

I am not new to FreeBSD, but I am new to X11. Xorg finished installing, so
I should be able to configure and test it.

#pico /usr/local/etc/xorg.conf

I tried the same with generic vga driver

#Xorg -config /usr/local/etc/X11/xorg.conf
...
(EE) No devices detected
...

#pico /var/log/Xorg.0.log
...
(--) PCI:*(0:16:0) nVidia Corporation NV11 (GeForce2 MX/MX 400) rev 161,
[...]
...
Pardon my paraphrasing, but I have to retype what I see. It seems to load
the nv driver ok, but it can't find the card.

the nvidia drivers are i386 only.

Do I need agp or something for this card? What am I doing wrong? Any help
is greatly appreciated.
