I could see it removing kmod-foo-1.2.2.6.17-1.2171_FC5, but why does it also
remove kmod-foo-1.2.2.6.17-1.2157_FC5? Wouldn't that be in a different
module tree?

Also, with the kabi stuff, the Requires should get done automatically to an
ABI version. If the next kernel has an ABI change, and you rebuild the
module, thats cool, it picks up the new ABI in the automatic Requires. No
manual intervention.
I would _really_ like to get JCM involved in this discussion, especially on
the proper place to drop these modules so that a respin for one kernel won't
remove modules from an older kernel.
