Yes, that's what he means, I am called Alex very often, as Axel isn't
really that common, so no problem here ;)

This looks wrong, as 2.4.22 is greater than 2.4.20.

There is no epoch in ATrpms' kernels. Maybe some other wierd
dependency is pulling in the kernel?

I'll test myself on RH9 and get back to it :)

My personal view about the kernels is that I would like to merge the
features of PlanetCCRMA and ATrpms' kernels. Helpers are more than
welcome, especially when they feel kernel hacker blood in their
veins. ;)

Short description: One of PlanetCCRMA's kernels, as well as all
ATrpms' kernels are based on RH's base kernel adding some
features. These would probably fit together very nicely.

But Fernando has need for some features (low latency and some other
patches) which are more difficult to patch into RH's kernel, so he
packages Linus kernel with the required patches, too.

It would be nice, if we could get those parts together. Currently
neither Fernando, nor I have much time, so helping hands are very much
appreciated. If someone succeeds in putting the patches together,
packaging is not an issue.
