FreeBSD will not boot

[Adam Stroud]

All:

I updated my nvidia drivers from the ports collection (Using the
WITH_LEGACY_GPU_SUPPORT option to add support for my GeFroce2 GTS). 
During the upgrade process, my machine rebooted on it's own and now
when I boot I get the following error message:

Anyone have any ideas?
