The best bet would probably be to migrate to TKL v11.x but if that's not an option then there are a few different ways to go. Personally I'd look for a PPA that contains the right version (compiled for Ubuntu 8.04/Hardy) but you will not be able to rely on it providing security updates.
The only really reliable way to do it is build from source but you will need to rebuild everytime there is a security update. Google and/or Ubuntu forums may give you some other ideas?
With great pain!
