Hi,

 I am using a April 12th 2007 build of DRM/Nouveau and experience rendering garbage at the top and the bottom of the screen.
The garbage is mainly colored without any "MigrationHeuristic" option set,
with the attached xorg.conf is consists merely of gray-shaped rectangles (see screen capture).

++lspci++

Tell me how I can be of an help,
