Back up your root partition, repartition, recreate the root
filesystem, and restore from backup. Even if you could extend the
partition using something like Partition Magic, I don't know of any
currently existing tool that allows you to resize an ext2 filesystem.

This is even less doable. Partitions can't span disks. You could
possibly use RAID to do this, but I'm not sure if it would work for a
root partition, and in any case I think you might be trying to solve
the wrong problem.

I think what you want is to have several partitions. For instance,
it's quite reasonable to have separate partitions for /, /home, /usr,
and /var.
