It is pretty simple, it builds/depmods the .kos and puts them in an
"update" directory in the /lib/modules (every distribution like to call
this "update" dir differently, even Debian vs. Ubuntu IIRC).

Whenever you load the module, it uses the one from "updates". What could
have happened is that you already had the old one loaded. Then you need
to "rmmod drbd" to get rid of the old one, and "modprobe drbd" to load
the new one.
