Update: 95% battery after 4 hours on and off, mostly off. 71% eDGe idle (not cell standby), 25% WiFi, 6% display. I know that doesn't add up, but it's significant that there is no cell standby in the list, which used to be listed as a second eDGe idle entry and took most of the battery draw. This is very encouraging.
I was talking with an engineer about the system mod, and he proposed a theory that if there is no antenna and the system ping is not returned, Android starts increasing frequency and amplitude of requests, so the process battery draw is actually greater on an Android device without a cell antenna than with. Neither of us knows if this is true, but it may be interesting to investigate.
I've seen all sorts of theory on both sides regarding removing phone.apk and power savings; usually theory comes down on the "no difference" side while anecdotal experience comes down on the other. I'll always go with experience, but some benchmarking may be in order.
