Look at the output of kldstat -v. Modules kld have many to one relationship;
one kld usually have several modules, with the name not directly
related to kld itself.

E.g., tp check what is in kld "linux"
x% kldstat -v -n linux
Id Refs Address            Size     Name
25    1 0xffffffff81a75000 1f76e    linux.ko (/boot/kernel/linux.ko)
        Contains modules:
		Id Name
		139 linuxelf

and then
x% kldstat -m linuxelf
Id  Refs Name
139    1 linuxelf
