Ok, the Volume Group now has /dev/hda5 added.

Well, of course!
You have increased the partition (/dev/Volume00/LogVol02).
You have *not* increased the filesystem /home.
Instead of lvextend you should have used e2fsadm which runs both
lvextend and resize2fs (or ext2resize), and fsck, in the correct
order. It's a good idea, generally, to umount /home first.
Please read the manpages of e2fsadm, resize2fs and ext2resize
for more information.
