Copy /usr/src/sys to somewhere else and then re-cvsup (if you've added 
new files/directories, be sure to remove them from the tree before 
running cvsup to be sure you have a "clean" tree).  Run a diff between 
the 2 places.

I find the easiest way to keep a custom tree up-to-date is by checking 
out the repository itself via cvsup (see 
/usr/share/examples/cvsup/cvs-supfile).  You can then do a cvs checkout 
of the source from your mirrored local cvs repository.  An update is 
then a 2-step process where you first update the repository via cvsup 
and then update your tree from the local repository via cvs.

 From the handbook section on cvsup (the cvs-supfile example uses this):
"There is an important special case that comes into play if you specify 
neither a tag= field nor a date= field. In that case, you receive the 
actual RCS files directly from the server's CVS repository, rather than 
receiving a particular version. Developers generally prefer this mode of 
operation. By maintaining a copy of the repository itself on their 
systems, they gain the ability to browse the revision histories and 
examine past versions of files. This gain is achieved at a large cost in 
terms of disk space, however."

To generate a diff is just running "cvs -R diff -u" (no need to have 
write-access; this also allows any user to do it).  A bonus is that you 
get the specific revision you're diffing from.  See this example diff:
