Well, CD5 had just finished installing when I went to bed last night, did the minimal configuration required this morning, and I have to say this is one niiiice distro. Really, my only gripe is still bug #113524, but I've now uploaded YaST logs for it, which will hopefully help. It's not insurmountable (no pun intended) though, copy /etc/cryptotab from your previous install onto a removable disc of some kind (I stuck mine on my USB drive) and then copy it back into place post-install, then simply reboot and you will be prompted as normal for the passphrase (or to avoid rebooting, run /etc/init.d/boot.crypto start - have fun guys.
