I would encourage you to please run uname -a on your own box before
beating up the newbie.  I think I understand where his confusion lies.
 I checked the output on two of my boxes:

# freebsd-update fetch
Looking up update.FreeBSD.org mirrors... 4 mirrors found.
Fetching metadata signature for 8.2-RELEASE from update3.FreeBSD.org... done.
Fetching metadata index... done.
Inspecting system... done.
Preparing to download files... done.

No updates needed to update system to 8.2-RELEASE-p4.
# uname -a
FreeBSD 8.2-RELEASE-p3 FreeBSD 8.2-RELEASE-p3 #0: Tue Sep 27 18:07:27
UTC 2011     root at i386-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC

All my machines are up to current patch level, but show p3 when I run uname -a.

I'm not confident that you are correct here.  See above.  Either p3-p4
did not touch the kernel, or the OP has a legitimate question.
