Comment(by xbaldauf):

 By the way, the bug also appears under kernel
 http://git.openmoko.org/?p=kernel.git;a=commit;h=e515295f2d76beff3986cc681b5e4da78bd9f484
 (The "stable" series of openmoko kernels, Mon, 9 Feb 2009 13:35:23 +0000
 (13:35 +0000) ). Logging in into the GSM network was okay, but placing a
 call triggered the bug.

 Note that, when "moving" a part of the screen after the bug was triggered
 (e.g. pushing the "middle button" in the englightenment UI to get a menu),
 the noise is moved with the part of the screen, it is not overwritten
 immediately.
