you'll need to shunt all the contents to one end of the partition first, and i don't know how to do that... if it were me i would tarball the partition's contents, then copy the tarball to a removable disk (or more likely another partition), then boot from a floppy or maybe use knoppix, and replace the / partition with my two new partitions, then still in knoppix (or my floppy linux, probably tomsrtbt), i would untarball the tarball onto the new / partition, edit the fstab file to reflect the new partition numbers and reboot with fingers crossed.
