The old modules are not fixed up by postinstall, and they
probably should not be either...

The reason is that may be used with -E or -D /, i.e.
installing into the currently running system.  The
script has no idea whether you later want to revert back to
running the kernel from the previous release number.  If
postinstall were to clean out the modules when the version number
is bumped, no compatible kernel modules would remain if you
wanted to downgrade the kernel.

On the other hand...  When you install the fresh -current
user-land into /, you have pretty much cut yourself off from
being able to run an older kernel, since there's no guarantee
that a new user-land will be able to run with the old kernel.  So
maybe the old kernel modules should be removed anyway, and what I
said above was wrong, and this ought to be handled better. :-)
