geom_label cannot be unloaded:

root@antsrv1 [~] # kldstat
Id Refs Address    Size     Name
  1    8 0xc0400000 3c8ed4   kernel
  2   14 0xc07c9000 56270    acpi.ko
  3    1 0xc3c38000 17000    linux.ko
  4    1 0xc9610000 4000     geom_label.ko
root@antsrv1 [~] # kldunload geom_label
kldunload: can't unload file: Operation not supported
root@antsrv1 [~] #

Am i missing something?
