well, Xorg -version says
X Protocol Version 11, Revision 0, Release 6.7

I think it was installed by sysinstall as a package.

I downloaded the drivers from nvidia.

the device section:

Section "Device"
         Identifier  "MyGeForce"
         Driver      "nvidia"
         VendorName  "NVIDIA"
         BoardName   "GeForce4 MX 440"

the sysctls:

hw.nvidia.agp.card.rates: 4x 2x 1x
hw.nvidia.agp.card.fw: supported
hw.nvidia.agp.card.sba: not supported
hw.nvidia.agp.card.registers: 0x1f000017:0x00000000
hw.nvidia.agp.status.status: disabled
hw.nvidia.agp.status.driver: n/a (unused)
hw.nvidia.agp.status.rate: n/a (disabled)
hw.nvidia.agp.status.fw: n/a (disabled)
hw.nvidia.agp.status.sba: n/a (disabled)
hw.nvidia.version: NVIDIA FreeBSD x86 NVIDIA Kernel Module  1.0-6113 
Mon Aug  2 16:08:32 PDT 2004
hw.nvidia.registry.EnableVia4x: 0
hw.nvidia.registry.EnableALiAGP: 0
hw.nvidia.registry.NvAGP: 1
hw.nvidia.registry.EnableAGPSBA: 0
hw.nvidia.registry.EnableAGPFW: 0
hw.nvidia.registry.SoftEDIDs: 1
hw.nvidia.registry.Mobile: 4294967295
hw.nvidia.registry.ResmanDebugLevel: 4294967295
hw.nvidia.registry.FlatPanelMode: 0 GeForce4 MX 440 16 AGP

kernel is basically the default one, built with agp device.

I *am* getting the acceleration, however, something is not quite right.

As i said, tuxracer runs just fine, so maybe it's some OpenGL feature
which most of the apps use, but tuxracer doesn't?

Anyway, i should probably try updating everything to the latest
versions and see what happens then.
Not so sure that it would help though :(

One more thing, I can't find any line in Xorg config relating
to agp. How is it enabled?
