That's what I thought (and currently have).

A custom kernel configuration file is *not* overwritten by
freebsd-update, I can confirm this. Of course I will have to compile and
install my custom kernel manually.
For some reason I was under the impression that /usr/src/sys is not
being updated by freebsd-update if I remove "kernel" from the
"Components" directive in freebsd-update.conf. But I might be wrong (I
will check).
Maybe related to this: how does freebsd-update "know" what
sources/binaries to get when I don't use the "-r" switch? Does it rely
on /usr/src/sys/conf/newvers.sh?
Could it be that I never saw a change to my kernel sources
(/usr/src/sys) because freebsd-update was tracking some static sources?

That's what I am planning to do. Let's see.
As I currently have a checkout from SVN in /urs/src I need to get rid of
this. Can I just copy (read: move) back my previous /usr/src directory
and continue to use freebsd-update? I think this should work, right? I
am just not sure if freebsd-update still "knows" what sources/binaries
to track (see my previous comment about how freebsd-update knows what
source to use).
Cheers
