Partition Management Software for Linux?

Chris Siebenmann is curious about the following: "As part of thinking about disaster recovery for our Linux machines, I'm looking at ways to back up and restore the partition tables of our disks, because it's about the only piece of data about the system that isn't backed up. We've got printouts of the partitioning details (via 'fdisk -l' and 'cfdisk -P') but I'd rather not go through the error-prone bit of typing them in again to partition new disks. Is there any program that saves and restores partition tables? Better yet, is there one that saves partition tables in some reasonably abstract levels, describing the size of the partitions and how they're structured in an editable form, with a restoration program that can cope with a not-completely-identical disk to restore them onto? (Such a program would be a useful part of an automated Linux setup and install system, too.)"
