As mentioned Benjamin, it is hard to boot a distro without sysfs. I 
think it is a good idea to use the lxc patchset.

You can use the latest version:

http://lxc.sourceforge.net/patches/2.6.27/2.6.27-rc6-lxc1/

If you want to play with the container, you have the userspace tools at:

http://lxc.sourceforge.net/download/lxc/

Don't forget to check the README in the directory ;)
