Yes I am using the nvidia driver that is from x11/nvidia-driver.  I guess 
since I don't have the system boot into X, this didn't occur to me.  It 
makes sense that the problem is this driver getting loaded at boot since it 
is in my loader.conf and the CD doesn't have that.

I figured it would be something simple I was tripping on.  Thanks for the 
help, I will try it and see how it works out.
