Bear in mind that i don't have an eDGe, so I may not be that useful, but I have some experience with other embedded devices, and I do have a hacked version of android running on my HTC Touch.

EDIT: I realized that this post didn't really have a point. What I'm saying is I'd be interested in helping, but some of it might be difficult given that I don't have a device. I'm here to ping ideas off of or I'm willing to help with linux questions, if that's useful.
