A new friday - a new status report:

I tried it with arb_rewrite2.patch and also with

[PATCH 1/3] drm/nouveau: Update the CRTC arbitration parameters on FB depth
switch
[PATCH 2/3] drm/nouveau: Clean up the arbitration parameters calculation code.
[PATCHv2 3/3] drm/nv10-nv20: CRTC arbitration code rewrite.

X works but console has flickering artifacts with both.

Yes, but there are other artifacts: E. g. bottom left and bottom right
"Position" line or "Gamma" with corrupted last "a" and "Mehrere Monitore" with
corrupted last "e".

Do you need a current dmesg?
