Subject: [PATCH] Reset available offscreen segment save function pointer. (Not
 a functional     change, just cleaning up a bit) Reset the
 screen->memory_base value when frame buffer is remapped. This     makes sure
 new off-screen allocations point at the newly mapped region     rather than
 the old (now unmapped) region.
