yep. dd does raw byte copying; you successfully wiped out your new
reiserfs and dumped a binary image of your old fs onto it :)

i THINK you can just do this (assuming all partitions are mounted)

make the backup:
tar -czvf /where/hda7/is/mounted/backup.tgz /where/hda2/is/mounted/

then create the reiserfs partition on /dev/hda2 (assuming you're not
booted from there)

mount /dev/hda2 somewhere
cd somewhere
tar -xzvf /where/hda7/is/mounted/backup.tgz

then if /dev/hda2 is your root partition (i'm not clear from what you
said) edit somewhere/etc/fstab appropriately

and if you /boot is on /dev/hda2, you'll need to run lilo
telling it to use somewhere/etc/lilo.conf (i forget what flag you
use ... man lilo) ... unless of course you don't use lilo :)

sorry for not being more clear, i haven't done this in a year or two.
