Looks like a bad pointer passed to strlen().  Looks like the nvidia  
driver was doing a printf("Warning Device driver\"%s\"", foo) and that  
foo is a bad pointer somehow.  Actually, this looks like it's in the  
FreeBSD driver code rather than in the nvidia driver.  In fact, it's  
probably this code:

         if (devsw->d_version != D_VERSION_01) {
                 printf(
                     "WARNING: Device driver \"%s\" has wrong version  
%s\n",
                     devsw->d_name, "and is disabled.  Recompile KLD  
module.");

You probably need to recompile your nvidia driver as the kernel has  
changed the devsw ABI since the last time you compiled it.
