You will need to fetch the FreeBSD source tree first:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/current-stable.html#STABLE

If you still have your installation CDs, you should be able to run
sysinstall and just reinstall the src distribution ( Configure ->
Distributions -> select 'src', select 'All' ).  

Then you can apply the patch.
