"De-tuning" Modern skin

[ndspeed3]

Is there a way to de-tune winamp in order for it to use less system resources? On the computer in my room it only has a 400 mhz CPU, and the modern skin eats up resources like a turkey sandwich. The reason I still wanna run the modern skin is that many of the options such as crossfading and scaling are only availible witht the modern skin. Thanks for the help in advance!
