Now that I've got my stock of Compacs (6 via-via + the 2 direct that I'll keep, bitshopper hasn't opened sales yet unfortunately), I finally updated the packaging stuff. The booklet remains much the same, other than the change in pot direction and a few wording and URL changes.
The back now has a bit of text and puts the GekkoScience logo over the heatsink:

I'll send GekkoScience a box along with some other goodies (@sidehack: is the send-from address you've been using also the mailing address to use?).
If anybody wanted to use it as a basis for their own, the InkScape design files are up here (for as long as that URL is valid):
http://www.filedropper.com/gekkosciencecompacpackaging-quartetsizeThe box is a "quartet" size PP box, which is larger than a poker card size box. The Compac won't fit (well) in most poker size boxes length-wise, so if you were to get boxes, just keep that in mind.
Included in the design files:
