kldload: can't load nfssvc: File exists

but:

vm-salwerom% sudo kldload nfssvc.ko
vm-salwerom% dmesg | tail -n 10
em0 at 194.29.146.128 server 194.29.146.27 server name amp2

Trying to mount root from nfs: []...

so, why if I want to load nfssvc I have to type it with the suffix? How can 
I tell nfsuserd and anfscbd to try to load it with suffix during system 
boot?
