RFE: smart upgrade automatically installing kernel modules for new kernels?

I've just implemented two new hooks in Smart, and committed to the
development trunk. They are "cache-loaded" and "cache-loaded-pre-link".
The one you want is the second. It will be run after all packages have
been loaded into the cache, but before relationships have been linked
to build the in-memory graph.

The test in tests/load-hooks.txt artificially inserts an upgrade relation
between two packages, in a way similar to what you want to do, and should
give you a hint about how to do it. For RPM packages, you can get the real
upgrades relation from

    smart.backends.rpm.base.RPMUpgrades

You can also use the cache that is passed as the first argument to the
hook to investigate which packages are available, to conditionally
insert the relationship the way you want.

Please let me know if you managed to build the plugin you wanted with
this, or if you need any help.
