This scheme was discussed back in the fedora.us days, what I remember of
this particular topic is that people couldn't agree on whether the name
should be kernel-smp-foo or kernel-foo-smp. :) Also with that scenario
you'll loose the direct uname-r relationship complicating some other
things while solving another. As typically happens with kernel module
packages...

Hmm.. if yum would just prefer installed packages providing something
instead of "whatever happens to be available in whatever order they
happen to be encountered" it would solve at least part of this problem.
Oh and if you have both up and smp kernels, well you probably should
have both kernel-module variants. And then there's the question of what
kernel version yum should install the module for - whatever is currently
running isn't necessarily the latest etc. No matter what path I've
followed with these, I've always ended up *something* requiring some
naming hacks depending on uname -r output :-/
