Comment 3 for bug 898224

No, this won't be backported or SRU'd to earlier releases. If you feel daring, you may wish to try out Precise Pangolin early, and help with the testing... see here: http://www.ubuntu.com/testing

Since Alpha 1 is the only milestone released so far, you'll need to make sure to update to the latest packages too; which may prove to be complicated for testing without installing on your system (but you can still install on a virtual machine or so).
