I have just updated Aardvark Post-IT.
There are 2 releases of the same theme. However one is for Moodle 2.1 and the other is for Moodle 2.2
You can download the version you need from the Plugins page here...
As well as fixed the theme for some minor bugs, I have also added a much needed Custom CSS to the settings page, which will allow you to modifiy this theme to your hearts content.
