I'm not a grub expert, so I hope I don't spread misinformation...
First of all make sure you do edit the right grub.conf.

I do not understand your 'root=LABEL=/1' I would have tried it like this:
title Red Hat Linux (2.4.26-1.ll.rh90.ccrma)
kernel (hd0,4)/vmlinuz-2.4.26-1.ll.rh90.ccrma root=/dev/hda6
initrd (hd0,4)/initrd-2.4.26-1.ll.rh90.ccrma.img
This assumes that vmlinuz and initrd are on /dev/hda5.

I don't think that you really want 'mount /dev/hda1 /mnt/rh8' as your
RH8 is not on /dev/hda1 but /dev/hda2. So you did mount '/boot' on
/mnt/rh8 which has no '/etc' directory...
BTW If you'd mount /dev/hda2 on /mnt/rh8 it's /boot wouldn't be mounted
either, as you have it on a separate partition.
BTW You could use the same swap partition for both systems.
