There is an ext3 patch for older 2.4 kernels (maybe 2.4.19 is the most
recent one at sourceforge, URL below though I can't seem to access SF
right now), but I'd have a hard time believing it would apply without
any tweaking to an RH kernel.  That said, the "technology" for doing ext3
online resizing hasn't changed very much for years so it wouldn't surprise
me if you could take the 2.6 patch and apply it to a 2.4.21-rhel kernel
with only minor fixing.  You won't get RH support for same, but it will
probably work.
