The above timings are screwed. This is 1024x768 at 85Hz INTERLACED.
The fb_find_mode() function picked up this mode when you specified
1024x768@75, since there is no such mode in the mode database.
And the atyfb driver accepted the mode without differentiating between
interlaced and non-interlaced.
Try the following modes instead (all present in the mode database):
1024x768@60, 1024x768@70, 1024x768@76, 1024x768@100. You can also try
1024x768@85 but you might get the interlaced mode again.
