Please see the attached patch for today's 180.29 NVIDIA FreeBSD graphics driver release. The following steps illustrate how to apply the patch to the official tarball:
# tar zxf /path/to/NVIDIA-FreeBSD-x86-180.29.tar.gz
# cd NVIDIA-FreeBSD-x86-180.29/
# patch < /path/to/NVIDIA-FreeBSD-x86-180.29-3459799.diff.txt
# make clean install
If you're installing on FreeBSD 8.x-CURRENT, you will need to manually remove the sanity check from
src/nv-freebsd.h.
