SOURCE: coolant leak/head gasket
it is possible that the higher rpm is creating more pressure in the cooling system and forcing the antifreeze into the cylinder, if you know how, do a compression test on the engine and observe the plugs as you pull them for moisture..............however i am thinking that you may have to wait until the problem with the smoke gets worse in order to determine which cylinder is leaking

SOURCE: white smoke from exhaust
The white smoke is from coolant entering the combustion chamber(s). Coolant can enter through the water passages sealed bu the head gasket. You have probably blown a head gasket. You should check your coolant level. You may have acracked head if you continue to drive it and overheat. The temp gauge only reads when exposed to coolant, not air. Take out thhe spark plugs and look them over. A white glossy apperance will indicate water in the combustion chamber. You may need to surface the head once you have it removed so that it is flat. Hope this helps.
