Downgrading a Kernel within the series released for a particular
distro is usually pretty easy. Up or down -grading to something not
packages for a distro can me a lot more work.
No version of Red Hat has ever used 2.3.x kernels. However, RHEL4 uses
2.6.9-XX and RHEL3 used 2.4.21-XX, so I'm guessing you meant
2.4.21-47.ELsmp (??).
If this is in fact the case, then you need to get yourself a RHEL3
workstation to test on. You won't get a 2.4 kernel to work on RHEL4
and newer because a lot of the rest of the system expects a 2.6 kernel
of some kind. There a lot of things that are done different between
2.4.x and 2.6.x for example udev for devices.
You should have no problem installing a specific version of 2.4.21 on
RHEL3 though.
