However you can use BLKPG_ADD_PARTITION to add a new partition providing it doesn't overlap any existing partition. Unfortunately parted doesn't use this ioctl, nor am I aware of anything which does. (Google suggests something called DeviceKit does, but I know nothing about that). You could write a program which reads the the partition table and tries to add each partition individually. Some might fail but others might succeed. ... or maybe you don't need to- 'partx' in util-linux-ng seems to do what you want.
