The 'no static devices' rule is something that Greg brought up at the embedded developer session during PlumbersConf this year, I wasn't aware of the problem before that either. It is not related to the multi-platform kernel work and it's not ARM specific. Maybe Greg can give a short explanation of the impact of this. AFAIR, static device definitions still work, but there are plans to remove that capability in the future.
