I installed the 7174-drivers on my FreeBSD 5.4-STABLE box, but when I start UT2004, the game lags big time. I also tried glxgears, but I only get 2/3 of the score that I'm getting in Slackware 10.1 @ 2.6.10, also with 7174 for linux i386. My video card is a GF6800GT 256 MB GDDR3.
Edit: I also got the same symthom in FreeBSD 5.3-RELEASE.
Edit edit: when I run nvidia-settings, my video card is listed as a PCI card, although it is an AGP-card.
I can also list up my spec's on my computer as well:
P4 NW 3.0 GHz
Asus P4C800-E Deluxe
Corsair TWINX-PRO3200XL 1024 MB
Creative Audigy 2 Platinum
Seagate Cheetah 15K.3 36.7 GB
Edit Edit Edit:
Problem solved. Added hint.agp.0.disabled="1" in /boot/device hints and hw.nvidia.registry.NvAGP=1 in /etc/sysctl.conf. The module agp.ko was the reason to all my problems, I must use NvAGP instead of the FreeBSD AGPGART driver.
