parted then gave:
Warning: The kernel was unable to re-read your partition table, so you need to
reboot before mounting any modified partitions.  You also need to reinstall 
yourboot loader before you reboot (which may require mounting modified 
partitions).
It is impossible do both things!  So you'll need to boot off a rescue disk, 
and
reinstall your boot loader from the rescue disk.  Read section 4 of the Parted
User documentation for more information.

That worked OK with a boot floppy.

# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda3             3.2G  2.1G  1.0G  68% /
/dev/hda2              61M  5.7M   51M  10% /boot
/dev/hda1             1.0G  728M  299M  71% /mnt/windows
none                   58M     0   57M   0% /dev/shm

OK, after checking on the LUG archive, I've got ext2resize but I can't 
actually work out how to implement it!

ext2resize v1.1.17 - 2001/03/18 for EXT2FS 0.5b
usage: ext2resize [-d] [-f] [-i] [-q] [-u] [-v] [-V] device new_size[bkmgt]
               -d, --debug    : turn debug info on
       -f, --force    : skip checks
       -q, --quiet    : be quiet (print only errors)
       -u, --unsafe   : skip buffer cache flushing
       -v, --verbose  : be verbose
       -V, --version  : print version and exit
       new_size is in ext2 blocks (1k, 2k, or 4k) (default),
       disk Blocks (512 byte), Kilo-, Mega-, Giga-, or Terabytes

So would it be /dev/hda3 4.2G  ?

The ext2resize program does not manipulate the size of the
      device. If you wish to enlarge a filesystem, you must make
      sure you expand the underlying device first. This  can  be
      done using fdisk(8) for partitions, by deleting the parti­
      tion and recreating it with a larger size (assuming  there
      is free space after the partition in question).

Maybe not.

So /dev/hda3 can't be enlarged to include the spare space BEFORE the starting 
cylinder?
