<pre>I can confirm that disabling ColorTiling2D had a positive impact.
There were no black screens on resuming the monitor from powersave mode.
I ran the system for about 14 hours. Then I turned ColorTiling2D back on,
and hit the issue within 5 minutes. The monitor power LED is on when resumed
and I can see the backlight. I tried switching to VT and still a black screen.
I do see (via ssh) the the lines you mention (in <a href="show_bug.cgi?id=75357#c7">comment 7</a>) in my xorg.0.log
when trying to switch VTs. Let me know if you want the full log, following is a
snippet from the log:
