Their "website" looks like a scam. They seriously couldn't be bothered to write ANYTHING up about it? As far as getting a computer working on all open source software, probably the easiest approach would be to hack/re the lower level bootloaders for snapdragon. With those out of the way, you can run basically a whole computer (like an ifc6410) on entirely open source software. Yeah, a few things won't work, but probably not critical stuff, like the built in GPS.
