Well, good news is, it'll boot up and work when docked. Though seems at present, if I try to enter the hb app store even with the DNS MitM HOSTS file in place, it also insta-crashes Atmosphere at the moment.
**Update** Good thing such homebrew is easy enough to find with Google. updating that, sigpatches, and things are coming back together. Whew...!
