Michael, I have done this (with ext2 file systems, but they are the same
on the disk) using gnu parted.  You can use it to extend a partition without
deleting the existing partition!  No loss of data.  The only requirement is
that the larger partition is an extension of the original, and starts in the
same place.  Otherwise, you have to delete and copy.  Gnu parted allows
that, too.

Basically, you download a two-floppy "boot-root" set and boot from it
to fuss with the partitions on the hard drive.  You can also run from linux
and modify UNMOUNTED partitions.
