Not sure I would apply insane to 4GB, but it definitely applies to >= 16GB, likely >= 8GB. Enough known deadlocks in this case. I would consider >=16GB on 32bit at least a kerneloops worthy condition.
Perhaps the warnings should vary in urgency. e.g. if it's >= 16GB and not 2:2 split we know that the system will have problems and it should strongly suggest, otherwise weakly.
Or perhaps it should be measured in percentage of mem_map in lowmem?
