I had opportunity to go through my stash of AGP NVidia graphics cards.
The only one with DVI output was apparently toast and the machine wouldn't
complete POST.
Two others had voltage-specific slot keying and wouldn't fit the AGP slot
on the Intel D845EGB2 board I was using.
The remaining cards all worked, up to a point. As soon as the nouveau
driver attached and the display switched to the framebuffer console, the
only visible element was a bright block cursor. As it's position changed,
it was clear text was being displayed but it was invisible (black-on-black).
Relevant snippets of "dmesg.boot":

Anyone else playing with nouveau on i386 w/AGP? I have a pile of these
cards, so if someone with sufficient nouveau clue cares to bang on them,
I can supply a couple or three.
The only other AGP NVidia card I've had a chance to try was a Quadro 780
in an IBM IntelliStation ZPro and it worked OK for the framebuffer console,
but had problems with X.
I also checked out a PCI GeForce FX5200 and nouveau liked it just fine.
X worked but was decidedly sluggish--you could watch the FVWM root menu
being drawn.
There are a couple of other AGP NVidia cards hiding in some other machines
around here, but I haven't had a chance to poke at them yet.
