<div>it often blinks after booting, not only at boot time. whether using vesa kfb </div>
<div>would be better than geode kfb since geode lx kfb is very basic and not feature rich.</div>
<div>android uses opengl-es, not xorg server. like cfbcopyarea.ko, cfbfillrect.ko and so on,</div>
<div>are they related to kfb or drm? selecting these modules can improve display even without</div>
