Playing with colorTiling was unhelpful. Playing with resolution changes nothing. It simply doesn't work if i set DefaultDepth to 16 (for UMS). Disabling PAT support via nopat kernel option changes nothing.

in mainline. I halted git-bisect because original good/bad pair was not about this bug, i wrongly assumed new kernel was unable to "fix" bug 22576.
I can re-run git-bisect, but it will take time ... anyone want to beat me on this?
