Kernel modules are from the same build.

look at this:

vm-salwerom% kldstat
Id Refs Address            Size     Name
 1   19 0xffffffff80100000 711d58   kernel

 7    1 0xffffffff80a1b000 1fa      green_saver.ko
vm-salwerom% sudo kldload nfssvc
kldload: can't load nfssvc: File exists
vm-salwerom% kldstat

 2    1 0xffffffff80812000 85d0     procfs.ko
 3    2 0xffffffff8081b000 9628     pseudofs.ko
 4    1 0xffffffff80825000 68ad0    if_em.ko
 5    1 0xffffffff80a12000 2c92     geom_md.ko
 6    1 0xffffffff80a15000 50fb     tmpfs.ko
 7    1 0xffffffff80a1b000 1fa      green_saver.ko
vm-salwerom% sudo kldload nfssvc.ko <-------the suffix is needed
vm-salwerom% kldstat
Id Refs Address            Size     Name
 1   21 0xffffffff80100000 711d58   kernel
 2    1 0xffffffff80812000 85d0     procfs.ko
 3    2 0xffffffff8081b000 9628     pseudofs.ko
 4    1 0xffffffff80825000 68ad0    if_em.ko
 5    1 0xffffffff80a12000 2c92     geom_md.ko
 6    1 0xffffffff80a15000 50fb     tmpfs.ko
 7    1 0xffffffff80a1b000 1fa      green_saver.ko
 8    1 0xffffffff80a1c000 381      nfssvc.ko
vm-salwerom%


so I am able to load nfssvc.ko (with '.ko' suffix) ant unable to load nfssvc 
(without '.ko' suffix) - why ?
