Not all updates include kernel updates, some are just userland.
If you are running a GENERIC, unomdified (from CD) kernel, this will be 
updated in the process. freebsd-update shows you a list of updated 
files, and will also show /boot/kernel/kernel if this is updated. You 
will also see source files in /usr/src/sys being updated on a kernel 
update. Since I always run custom kernels, I just watch for changes in 
/usr/src/sys. If there are updates there and you are running a custom 
kernel, you will have to recompile it. Otherwise you don't have to. The  
uname -a command will still report a previous -p<version> until you 
recompile though.
