btrfs and lz4

[Perkabalo]

Excuse me for my noobyness, but how exactly would I install this?

What I''ve done:

# wget http://xbian.brantje.com/others/xbian-package-kernel1.3-6.11b-lz4.deb

# dpkg -i xbian-package-kernel1.3-6.11b-lz4.deb

changed cmdline.txt compress=lzo to compress=lz4

reboot.

But I guess there's something more to it, cause I end up in recovery mode, and have to switch back to compress=lzo to be able to boot.
