It does still happen, and I even still have the affected machine. Through further experimentation, I found that what was happening was that the actual fastest pixel clock which the integrated GPU could output was slower than what X was trying to use. So to work around it, I either reduce the total resolution, or reduce the framerate. It is possible that this is actually the monitor's fault; the modeline that it was using came from the monitor's EDID, and I have reproduced a similar issue on a different machine with the same monitor. If it's the monitor to blame, I don't know that it's really a problem for freedesktop to fix... It would be handy at the very least to be able to configure X not to drop back into the default highest mode the monitor suggests, if it's ever hot-swapped, but I don't see anywhere in the X configuration that that sort of setting could be hooked onto. I also theorized that the intermittent behavior was the result of allocating more video memory, but from cursory use of Intel's GPU tools, I was unable to find support for this. I stopped looking into it at that point, because I had a workaround already. I'll plug the original machine that the report came from back in at some point in the next couple weeks, and get you logs from it; I'll also try to get logs from the other affected machine, for comparison.
