I believe the Ubiquity Preserve Home spec was targeted and achieved for Hardy.
If I'm correct in this belief then you can indeed reinstall Hardy (and indeed
you could upgrade to a more recent version of Ubuntu, although of course this
is a matter of preference) without damaging the contents of /home, as long as
you specified a separate partition for it in your original installation.
If you did then you can run preserve /home quite easily (assuming I can
correctly recall the steps involved in doing so):
Run through the Ubuntu installer until you reach the partitioning stage
Choose manual partitioning
Select the partition with /home on it and choose to use it
Choose the correct filesystem, but also choose NOT to format it
Change the mountpoint to be /home
Setup your other partitions appropriately and finish the installation
Working from memory, that's the correct (and easy) procedure; it does hang on
the existence of /home as a separate partition already, though. You could work
around that by migrating the content to a new partition while preserving all
the necessary file attributes and then choosing this partition during
installation, of course.
It's probably best to wait for someone else to confirm the procedure to
preserve /home before you try, though; whilst I've done it many times, my
memory isn't always reliable and I'd rather that it wasn't responsible for the
loss of any of your data.
