I was trying to follow Ted's guidance on this and couldn't get chattr to add the extent option to the files. Ted told me by email to do this:
tune2fs -O extents,uninit_bg,dir_index /dev/yourfilesystem e2fsck -pDf /dev/yourfilesystem
(it required booting from a USB stick so I could access the filesystem while not running from it). The correct e2fsprogs is in Karmic.
