Subject: Fix bug in Lime video driver

We need to wait while drawing engine clears frame
buffer before any further software accesses to frame
buffer will be initiated. Otherwise software drawn
parts could be partially destroyed by the drawing
engine or even GDC chip freeze could occur (as
observed on socrates board).
