I've uploaded a seriously better CWM for our device, compiled from current source. It still identifies as 22.214.171.124.
Much better backup/restore and it works great with the Exhibit's external SD. This can be applied to any ROM via standard recovery, console or your current CWM. (Its menu says "internal sd" when it means "external sd". I'm aware of this. It may be an artifact of my current build setup)
