Sorry, yes, I have not posted on how to change spec files for the
kernel. I don't think it would be easy to describe...

The question was because I'm working (I'm posting this on a machine
running 2.4.22-1.ll.acpi :-) on a newer kernel based on 2.4.22 (which
was just released). It may be possible that the patches you need are
already included in 2.4.22. Could you send me an URL for those patches
so that I can check?

Nope, you can have multiple kernels installed (you _should_ have
multiple kernels installed, normally I always leave the original or
updated redhat kernel installed, just in case).
