Congratulations on the merge.

Eventually if both machines are going to run a standard Fedora
release, the same binary kernel will have to be able to run on both
(and figure it out at runtime, like it does with most other x86-based
systems).  I'm presuming from your message that that's scheduled to
happen some time ... later ...
