Sorry, that pasted badly, it should have read:

gohan10# uname -a
FreeBSD gohan10.freebsd.org 8.0-CURRENT FreeBSD 8.0-CURRENT #8: Sun Mar 
29 12:06:13 UTC 2009 
root_at_gohan10.freebsd.org:/usr/src/sys/amd64/compile/CLUSTER  amd64
gohan10# grep LOCK_PROFILING /usr/src/sys/amd64/conf/CLUSTER
options         LOCK_PROFILING
