Well, I was always against kernel's in Fedora Extras (and I still am,
[mostly]). But having a Xen non-PAE kernel in Extras sounds like the
proper solution for the above problem. But having kernels in Extras
would only be okay for me if
- they are build with the same spec-file as the other kernels
- they are build on the same build system in the same step as the other
- they are moved to the proper Extras repo in the same moment as the
other kernels are pushed out
There are some technical problems that probably would need to be solved
before the above could be realized, but that should be possible if we
really want to.
