We'll probably use suspend2disk for that since the originally planned hotswap under "full load" might not be feasible due to size requirements for the buffer capacitors and also they would need a precharge time anyway when we implemented them - same time could as well get used to suspend2disk and swapping batteries is not time critical then anymore. If we would do hot swapping, suspend2ram had no advantage over stopping a few processes resp blocking IRQs and shutting down a few peripherals. That's what maemo is all about, it shuts down peripherals and stops CPU clock whenever possible, you don't need any suspend2whatever for forcing that.
