Just as I thought. Even this breaks the nouveau driver.
Could you now add also in the drm_fb_helper_fill_fix function
DRM_INFO("pitch %d, depth %d\n", fb_helper->fb->pitch, fb_helper->fb->depth);
I have a feeling the values are not right. Thanks.
Please make an patch to test.
Done. I had to test the patch myself. No need to do a revert. Just apply this patch to linus tree. Then send the dmesg to me. Thanks.

I will test it, but first, I will need to disable the cassini driver, because it can not compile.
