It wouldn't be impossible, but might be difficult... the 2.4 kernel puts
some things in different places (proc and modules have modified layout from
2.2 for example), so some of the scripts on an older non-2.4 aware RedHat
may complain.

This is why RedHat 7.0 was considered "2.4 ready" even though it came with a
2.2 kernel.  All the scripts were aware of what might change if a 2.4 kernel
were dropped in.

RedHat 6.2 out of the box will throw some errors with a 2.4 kernel, but you
can download updated initscripts and modutils that fix everything.  I'm not
sure about 6.1 or earlier... might take some hands-on hacking, but I'm sure
it's doable.  Might not be fun though :^)
