No, people getting this problem are using i386 on an AMD 64 (there is no 
nvidia driver for amd64, you have to use the open source nv driver).

The problem, as I understand it, is that neither the FreeBSD nor the NVidia 
AGP driver works with the nvidia driver on some AMD 64s. Consequently you 
don't get the full data transfer rate of the AGP slot.

Personally I don't see any consequnces of this,  for example OpenGL works 
perfectly well on Quake 2.
