Use real double buffering instead. I checked the SDL code and if the hardware cannot provide double buffering it will use a shadow surface to ensure that a frame is not displayed until it has been fully painted. Also disable mouse cursor before opening the output surface. The reason it was disabled after the surface was opened is that SDL on GP2X has a bug. However, this means the cursor is visible for a short time during startup which looks ugly.
