The kernel module for the Rage 128 is named r128.o and should be
installed in /lib/modules/KERNEL-VERSION/misc/. It
will be automatically loaded by the Xserver if needed.

The DRI 3D driver for the Rage 128 should be in
/usr/X11R6/lib/modules/dri/r128_dri.so. This will be automatically
loaded by libGL.so.

"/lib/modules/KERNEL-VERSION/misc/"

This refers to a *Linux* kernel module, AFAIK FreeBSD can't run them
(would love to be wrong)....  

When I was running 4.01 in Linux I had to load the kernel module
*before* I did a 'startx' to enable DRI (this was for a Voodooo3).

Unless you specifically need something from 4.01, I'd stick with 3.3.6,
as it has better support for 3D at the moment.
