By virtue of the fact that kldstat(8) returns nvidia. You
can be assured that linux has already been loaded, or
rather, that linux is already available. Which suggests to
me that it is already part of your kernel. dmesg(8)
(/var.run/dmesg.boot) might well reveal that, for you.
Perhaps even in /var/log/messages.
