The problem is that kldloading a module if it's already in the kernel
can cause a panic.  Also if the module becomes stale with respect to
the running kernel, this approach can cause a lot of confusion.

Something I'd like to see is

a) Fixing the kldload "double load" problems

b) That optional kernel subsystems register themselves with a sysctl,
so that userland can easily determine whether a feature is present in
the running kernel and take appropriate action (warn user, demand
load, etc) if not.  compat[45]x support is another such case; there's
no way for a port to tell whether the kernel supports running such
binaries, and if not then the user will just get an error when they
try to run it.

I guess these should go on the "projects" list.  The second one would
be a good SoC project, for ex.
