Your luck is just that your kernel that claims to be 2.4 is really
essentially 2.6, so it's not as old as you think it is. My impression
is that "enterprise" vendors like RH like to stick with the version
number that was widely known as being stable and reliable at the time,
and end up applying so many patches/backports/local customizations
that the old version number is pretty misleading.

Anyway, if your goal is just to be able to run programs on this
version of RHEL, you should be fine! If you also need to run on other
old systems that print "2.4" as their version number, you probably
need to do further research.
