Thanks to the help on the Ubuntu blog, I got it set up and running with no problems, leaving a quick mount after the reinstall to get think back up and running. No more faffing around trying to get the machine setup as it was before... all the app specific information is already where it needs to be.
move /home /home1
mount /dev/sda1 /home
/dev/sda1 /home ext3 nodev,nosuid 0 2
