Let me use the output of svn info from stable/9 as an example:

root at enterprise:/usr/src # svn info
Path: .
Working Copy Root Path: /usr/src
URL: svn://svn.ximalas.info/freebsd/base/stable/9
Repository Root: svn://svn.ximalas.info/freebsd/base
Repository UUID: ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f
Revision: 245035
Node Kind: directory
Schedule: normal
Last Changed Author: pfg
Last Changed Rev: 245025
Last Changed Date: 2013-01-04 05:03:21 +0100 (Fri, 04 Jan 2013)

The uname string of the kernel includes the revision number contained 
in the Revision line as shown above. svn keeps global revision numbers 
unlike cvs which uses revision number per each file.

All of FreeBSD base source code resides in one giant repository. Thus 
changes made in, say, /base/head, i.e. -CURRENT, affects other 
"branches", say, /base/releng/9.1.

It would make more sense if the uname string referred to the Last 
Changed Rev line.

(Yes, I run my own svn mirror. It saves bandwidth when I issue 
svn log -v to look at the recent commit logs.)

BTW, do you nuke the contents of /usr/obj prior to recompiling the 
system? The command rm -Rf /usr/obj/* should accomplish this rather 
well.

Out of old habit I like keep everything clean before I issue 
buildworld + buildkernel with -DNO_CLEAN.
