 Thanks, I got the screenshot.
 
 That looks like the stride or width is wrong. My guess is that the
 stride is too short, judging by the way the bands are tilted. I'd
 recommend scribbling into video memory by hand - just draw a vertical
 line in the middle of a blank screen and make the kernel stop right
 there so you can look at it. That should make it more obvious where
 things go wrong.
 Might be a side effect of a video mode mismatch, something like the
 video hardware running at 800x600 and the drawing routines assuming
 640x480.
