Subject: tridentfb: acceleration bug fixes
From: Krzysztof Helt <krzysztof.h1@xxxxx>
This patch fixes two problems when acceleration is enabled:
- bit for bitblt direction is corrected
so scrolling down works as expected on 3DImage chips
- initialization of acceleration is done later
this helps with initial console malfuntion (on Blade3D
chips) well documented here:
