Hi,
By RELENG9, I mean checkout svn://svn.freebsd.org/base/stable/9


I am using a stock GENERIC kernel which seems to have those options.  I 
am building RELENG_9 on a RELENG8 machine, I wonder if this has 
something to do with it, but I use the same machine to build RELENG_10 
images and dtrace works fine on it.


options         KDTRACE_FRAME           # Ensure frames are compiled in
options         KDTRACE_HOOKS           # Kernel DTrace hooks
options         INCLUDE_CONFIG_FILE     # Include this file in kernel
options         KDB                     # Kernel debugger related code
options         KDB_TRACE               # Print a stack trace for a panic
options         DDB_CTF                 # kernel ELF linker loads CTF data
