The patch I was interested in 'only' improves boot time because the whole
kernel is LZO compressed.

 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=7dd65feb6c603e13eba501c34c662259ab38e70e

Basic LZO support was already there and can be used in certain filesystems
such as ubifs, jffs2 and probably some others.
