Maybe boot into rescue mode with a RHEL4 CD (linux rescue) and do your resizing there.

RHEL 4 should not require you to umount your partition. You can change it on the fly with newer versions of LVM.

That option is "ext2online" command (lvextend first).

However I vaguely remember there's a size limitation with "ext2online" command on a unprepared partition.

That's correct about ext2online.

The size limitation only affects ext2 filesystems, since it was not created with this in mind originally for changing the size on a mounted partition. And I would find it hard to believe if anyone is still using ext2, unless it's some legacy system, etc.
